[416] Class-X Class-Y Rated Capacitors Explained, EMI RFI Suppression Safety Capacitor

in this video i explained what is class X, Y Rated Capacitor, EMI RFI Suppression Safety Capacitor, What is X, Y Rating, how class x or classy capacitor work in circuit. class x capacitor is also known "ACROSS THE LINE CAPACITOR" it is installed between Line and neutral, while cass Y is connected between Line to Earth, and Neutral to Earth, Class-X / Y capacitors help to minimize the generation of EMI/RFI and the negative effects associated with received EMI/RFI in the circuit. to take a useful work from these capacitors to perform their EMI/RFI filtering tasks, the class X are directly connected to the AC power input, that is, the AC “line” and the AC “neutral” (see Figure 2 below). And because of this direct connection to the AC voltage, the capacitors may be subjected to overvoltages and/or voltage transients—lightning strikes, power surges. Thus, capacitor failure is a very real possibility.

When a Class-X capacitor, also referred to as an "across the line capacitor"—the capacitor placed between line and neutral—fails because of an overvoltage event, it is likely to fail short. This failure, in turn, would cause an overcurrent protective device, like a fuse or circuit breaker, to open. Therefore, a capacitor failing in this fashion would not cause any electrical shock hazards.

If a Class-Y capacitor, also known as the "line to ground capacitor" OR "the line bypass capacitor"—it is connected between line and ground—fails short, this could lead to a fatal electric shock due to the loss of the ground connection. Class-Y safety capacitors are designed to fail open. A failure will cause your electronic device to be subjected to the noise and interference that the capacitor would normally filter out, but at least there will be no fatal electric shock hazard.
