This rule applies to suppressing electromagnetic interference (Formerly known as suppressing radio frequency interference) Components of fixed capacitors and resistor capacitors, which will be used in electrical and electronic equipment and connected across power lines, with a voltage between power lines not exceeding 500V DC or AC RMS, or a voltage between any power line and ground not exceeding 250V DC or AC RMS, and a frequency not exceeding 100Hz. This rule specifies the applicable Various tests for suppressing interference capacitors. The relevant equipment specifications can also specify other circuit locations where capacitors that meet the requirements of the specifications should be used. This rule also applies to combined capacitors with two or more capacitors installed inside a casing. This rule also applies to the series components of resistors and capacitors (resistors are in the same housing). This rule also applies to the parallel components of resistors capacitors, but this resistor serves as the discharge anode of the capacitor. Capacitors used under special environmental conditions (such as water droplet resistance, waterproof fog, etc.) must meet additional requirements P>
Function of testing report:
