A polarized capacitor dropped into an AC circuit is a short circuit waiting for its moment. That is the practical difference between a DC capacitor and an AC capacitor, and it decides which one you are allowed to put in a given position. The difference comes down to what the oxide layer does when the voltage [...]

As a reactive power compensation device, power capacitor is an important equipment for safe operation of power grid. However, in actual applications, due to human factors and environmental factors, the capacitor frequently fails during operation, which affects normal work. This article introduces several common Fault handling of capacitors method. Fault handling of capacitors 1. When the capacitor explodes [...]

For example，SMD electrolytic capacitors lifetime on the surface of the chip electrolytic capacitor, a temperature data will be marked, such as 125 and so on. This temperature represents the maximum temperature that the capacitor can withstand. At this maximum temperature, the capacitor generally can only guarantee about 1000 hours of normal operation. Through this temperature value, [...]

1. Working principle of super capacitor The super capacitor container is mainly composed of current collectors, electrodes, electrolytes and separators. The role of the separator is the same as the separator in the battery. It isolates the two electrodes to prevent short circuit between the electrodes and allows ions to pass through. The basic principle of [...]

The full name of X capacitance is generally called: X2 (X1/X3/MKP) capacitor for suppressing electromagnetic interference of power supply. Generally, the main functions in the circuit are: power supply cross-circuit circuit, EMI filtering, spark elimination circuit, etc. to ensure that the finished electronic products meet EMC requirements. X capacitance: Since the location of this capacitor connection is [...]
