How much is the Zhongya safety capacitor

What is a Class Y safety capacitor?

These safety capacitors are also known by other names, including EMI/RFI suppression capacitors and AC line filter safety capacitors. (EMI stands for electromagnetic interference and RFI stands for radio-frequency interference; RFI is simply higher-frequency EMI.) Figure 1. An example of a Class-Y capacitor. Image from this teardown.

Are class X and Class Y capacitors safe?

Because Class-X and Class-Y capacitors must be connected directly to AC lines (line-to-neutral or line-to-ground) in order for them to perform their EMI and RFI filtering functions, they must be rated and certified as "safety capacitors." Both Class-X and Class-Y capacitors have subclasses: subclass X1, X2, and X3, and subclass Y1, Y2, Y3, and Y4.

What safety capacitors does Murata offer?

This presentation will review the added value and current safety capacitors offered by Murata. Murata's IEC 60384-14 Y1 class safety certified, surface mount ceramic capacitors for AC/DC power supplies. This presentation will introduce the X and Y safety capacitor lineup from Murata Electronics.

What happens if a Class Y capacitor fails?

If a Class-Y capacitor, also known as the "line to ground capacitor" or "the line bypass capacitor"—the capacitor placed 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.

What type of safety capacitor should I use?

Subclass X2 and Y2 are the most common type of subclass for applications that use 120VAC (USA) or 220/240VAC (Europe). X/Y combination capacitors are also available, so you might consider using one of these, as well. Whichever safety capacitor you choose, make sure that it has all the proper safety-approval logo markings.

What is a y2 safety capacitor?

Y2 safety capacitors are more robust, are able to withstand higher peak impulse voltages, and are designed to fail open as opposed to failing short. There are also safety caps that combine aspects of X and Y types, such that they have met both X and Y safety requirements and standards.
