electrolytic capacitors is a kind of capacitor. The metal foil is a positive electrode (aluminum or tantalum), the oxide film (aluminum oxide or tantalum pentoxide) which is in close contact with the positive electrode is a dielectric, and the cathode is made of a conductive material or an electrolyte (the electrolyte may be a liquid or Solid) is composed of other materials. Since the electrolyte is the main part of the cathode, the electrolytic capacitor is named after it. At the same time, the electrolytic capacitors are not connected correctly. Aluminum electrolytic capacitors can be divided into four categories: lead-type aluminum electrolytic capacitors; horn-type aluminum electrolytic capacitors; bolt-type aluminum electrolytic capacitors; solid aluminum electrolytic capacitors.
Polar electrolytic capacitors usually function as power supply filtering, decoupling, signal coupling, time constant setting, and DC blocking in power supply circuits or intermediate frequency and low frequency circuits. Generally, it can not be used in the AC power supply circuit. When used as a filter capacitor in the DC power supply circuit, the anode (positive electrode) should be connected to the positive terminal of the power supply voltage, and the cathode (negative electrode) should be connected to the negative terminal of the power supply voltage. Otherwise it will damage the capacitor.
Non-polar electrolytic capacitors are commonly used in speaker divider circuits, television S correction circuits, and start-up circuits for single-phase motors.
Electrolytic capacitors are widely used in household appliances and various electronic products. Their capacities range from 1 to 33000 μF and rated operating voltages range from 6.3 to 700V. The disadvantage is that the dielectric loss and the capacity error are large (the maximum allowable deviation is +100%, -20%), the high temperature resistance is poor, and the storage time is long and easy to be invalid.

inductor is an element that can store electrical energy into magnetic energy and store it. The structure of the inductor is similar to a transformer, but with only one winding. The inductor has a certain inductance that only blocks the change in current. If the inductor is in a state where no current is flowing, it will attempt to block current flow through it when the circuit is turned on; if the inductor is in a state where current is flowing, it will attempt to maintain the current when the circuit is turned off. Inductors are also known as chokes, reactors, and dynamic reactors.

The inductor is generally composed of a skeleton, a winding, a shield, a packaging material, a core or a core.

Inductors can be divided into: adjustable inductors, choke inductors, differential mode inductors, common mode inductors, power inductors, magnetic bead inductors, I-shaped inductors, laminated inductors, high frequency inductors, RF inductors, shielded inductors, winding Line inductance, color ring inductance, magnetic core inductance, three-pin inductance, high current manganese-zinc inductance, iron-silicon-aluminum magnetic ring inductance, chip inductor, plug-in inductor, horizontal inductor, rod inductor,

The inductor mainly plays the role of filtering, oscillation, delay, trapping, etc. in the circuit, as well as screening signals, filtering noise, stabilizing current and suppressing electromagnetic interference. The most common function of the inductor in the circuit is to form an LC filter circuit together with the capacitor. The capacitor has the characteristics of “resistance to DC, AC”, while the inductor has the function of “DC, DC”. If the DC current with many interference signals is passed through the LC filter circuit, the AC interference signal will be consumed by the inductor into heat energy; when the relatively pure DC current passes through the inductor, the AC interference signal is also turned into a magnetic sense. And thermal energy, the higher the frequency is the most easily inductive impedance, which can suppress higher frequency interference signals.
The inductor has the characteristic of preventing the passage of the alternating current and allowing the direct current to pass smoothly. The higher the frequency, the larger the impedance of the coil. Therefore, the main function of the inductor is to isolate, filter or form a resonant circuit with a capacitor or a resistor.

Bridge rectifier stacks are a wide range of power components. Used in a variety of power supply equipment. The internal is mainly a bridge composed of four diodes to convert the input AC voltage into the output DC voltage.
Bridge rectifier can be divided into GPP bridge rectifier and O/J bridge rectifier
During each duty cycle of the bridge stack, only two diodes operate at the same time, and the unidirectional conduction function of the diode converts the alternating current into a unidirectional DC ripple voltage. Dissection of the commonly used low-power bridge stack reveals that the full-wave bridge stack uses a plastic package structure (most low-power bridge stacks are in this package). The four main heating components in the bridge – the diodes are divided into two sets of pin copper plates placed on the DC output. There are two connected copper plates between the DC output pin copper plates, which are respectively connected to the input pins (AC input wires) to form a full-wave bridge stack with four external connection pins that we see on the outside. Since the series of bridge stacks are all in a plastic package structure, the above-mentioned diodes, lead copper plates, connecting copper plates and connecting wires are filled with an insulating and heat-conductive skeleton filling material – epoxy resin. However, the thermal conductivity of epoxy resin is relatively low (typically 0.35 ° CW / m, the highest is 2.5 ° CW / m), so the junction – shell thermal resistance of the Bridge rectifier stack is generally large (usually 1.0 ~ 10) °C/W).

fuse is also called a current fuse, which is defined by the IEC127 standard as a “fuse-link”. It is mainly used for overload protection. When the fuse is correctly placed in the circuit, the fuse will cut off the current when the current abnormally rises to a certain height and heat, thus protecting the safe operation of the circuit.

Fuse product classification

According to the protection form, it can be divided into: over current protection and over temperature protection. A fuse for overcurrent protection is a commonly used fuse (also called a current limiting fuse). Fuses for overheat protection are commonly referred to as “temperature fuses”. The temperature fuse is further divided into a low-melting alloy shape and a temperature-sensing shape and a memory alloy shape, etc. (the temperature fuse is to prevent the temperature of the heating appliance or the heat-generating appliance from being too high, for example: hair dryer, electric iron, rice cooker Pot, electric furnace, transformer, electric motor, etc.; it responds to the rise of temperature rise of the electrical appliance, does not care about the working current of the circuit. Its working principle is different from “current limiting fuse”).
According to the scope of use can be divided into: power fuses, machine tool fuses, electrical instrument fuses (electronic fuses), car fuses.
According to the rated voltage, it can be divided into: high voltage fuse, low voltage fuse and safe voltage fuse.
According to the breaking ability, it can be divided into: high and low breaking capacity fuses.
According to the shape, it can be divided into: flat-headed tubular fuses (also can be divided into internal welding fuses and external welding fuses), pointed tubular fuses, sickle fuses, spiral fuses, blade fuses, flat fuses, wrap fuses, SMD fuse.
According to the fusing speed, it can be divided into: special slow fuse (usually indicated by TT), slow fuse (generally denoted by T), medium speed fuse (generally denoted by M), fast fuse (generally denoted by F), extra fast fuse (Generally indicated by FF).
According to the type can be divided into: current fuse (chip fuse, micro fuse, blade fuse, tubular fuse), thermal fuse (RH [square type], RP [resistance type], RY [metal shell]), self-recovery fuse ( Plug-ins, laminations, patches).

Diode classification：Schottky diodes,rectifier diode,Zener diode,Bidirectional trigger diode,Solar blocking diode,Silicon carbide Schottky diode,Helium diode,Power diode,Discrete diode.
Among diodes and electronic components, a device with two electrodes allows current to flow only in a single direction, and many of them use the function of rectification. The varactor is used as an electronically tunable capacitor. The current directionality of most diodes is often referred to as the “rectifier” function. The most common function of a diode is to allow only current to pass in a single direction (called forward bias) and reverse in reverse (called reverse bias). Therefore, the diode can be thought of as an electronic version of the check valve.
The crystal diode is a pn junction formed of a p-type semiconductor and an n-type semiconductor, and a space charge layer is formed on both sides of the interface, and a self-built electric field is built. When there is no applied voltage, the diffusion current caused by the difference in carrier concentration on both sides of the pn junction is equal to the drift current caused by the self-built electric field, and is in an electric equilibrium state. When the outside is biased by the forward voltage, the mutual suppression of the external electric field and the self-built electric field causes the diffusion current of the carrier to increase to cause a forward current. When the outside has a reverse voltage bias, the external electric field and the self-built electric field are further strengthened to form a reverse saturation current I0 that is independent of the reverse bias voltage value within a certain reverse voltage range. When the applied reverse voltage is high to a certain extent, the electric field strength in the space charge layer of the pn junction reaches a critical value to generate a multiplication process of carriers, which generates a large number of electron hole pairs, and generates a large reverse breakdown current. It is called the breakdown phenomenon of the diode. The reverse breakdown of the pn junction is characterized by Zener breakdown and avalanche breakdown.
