Are there certification standards and marks for film capacitors?
Film capacitors generally do not have certification. This is not because manufacturers are unwilling to certify capacitors, but because there are no relevant standards. Which capacitors need to pass safety certification?
Why decoupling capacitors used for power rails should be very …
So placing a decoupling capacitor "far away" will make it do nothing as the impedance for the high frequency signals will be too high. So it needs to be close to the chip to be effective. $endgroup$ – Bimpelrekkie Commented …
Are there certification standards and marks for film capacitors? Which capacitors should be certified?
The varistor is not a capacitor, it is a resistor, and it also needs safety certification. The biggest advantage of the varistor is that when the threshold value of the varistor itself is greater than the voltage given by the outside, the current flow value in the circuit is very small, and its own valve will be equivalent to a valve that cannot work.
