XTN series standard capacitor is a kind of electrolytic capacitor. The horn electrolytic capacitor is a popular name, and the professional name is the conductive foil type electrolytic capacitor.
Compared with other lead-type electrolytic capacitors, horn electrolytic capacitors generally have the characteristics of large capacity and high withstand voltage.
Horn electrolytic capacitors usually play the role of 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 cannot be used in AC power supply circuits. When used as filter capacitors in DC power supply circuits, the anode (positive pole) should be connected to the positive terminal of the power supply voltage, and the cathode (negative pole) should be connected to the negative terminal of the power supply voltage. , otherwise the capacitor will be damaged.
In terms of current output, aluminum electrolytic capacitors occupy the second place in capacitors. This type of capacitor was originally a general DC capacitor, but now it has developed from DC to AC, from low temperature to high temperature, from low voltage to high voltage, from general type to special type, from general structure to chip, flat, book formula and other structures.
