One of safety-certified capacitors, JYA Class Y2 CE types capacitors, which are typically produced out of ceramic and paper dielectrics, are used with voltages up to 300Vac and a peak test voltage of 5 KV. JYA Y2 class certified product (basic insulation product) is a cross reference to Murata DE series.
In AC/DC EMC filter applications, two special classes of capacitors – Class-X and Class-Y – are used to filter AC power-source noise and are commonly referred to “safety capacitors”. Learn about where to use Class-X or Class-Y capacitors and what makes these safety capacitors critical for modern circuit design.
Class Y safety capacitors are used between the phase or neutral conductor and the accessible device housing. In this case, the base insulation is bypassed and, in the event of a safety capacitor failure, people may be put in danger. Therefore, Class Y safety capacitors must have elevated electrical safety. Class Y devices are subdivided into Y1
Ceramic capacitors class 2 have much higher capacitance values in a given case than class 1 capacitors because of their much higher permittivity. also known as safety capacitors, X2Y and three-terminal capacitors for bypassing and
A Special Class of Capacitors. Class-X and Class-Y capacitors are safety-certified and generally designed and used in AC line filtering in many electronic device applications. These safety capacitors are also known by other names, including EMI/RFI suppression capacitors and AC line filter safety capacitors. (EMI stands for electromagnetic
X and Y safety capacitors filter AC signals and reduce EMI, so they are directly connected to hazardous AC mains voltages and must be certified as "safety capacitors" to ensure safe operation under these conditions.
Safety Certified Capacitors are classified as either X and/or Y capacitors. Class X capacitors are primarily used in line-to-line (across-the-line) applications. In this application, there is no danger of electric shock to humans should the
Normally a Class Y safety capacitor is recommended for this, but a Class X safety capacitor could also be used. The idea here is that the connection allows high-frequency noise currents to pass between the grounds as needed rather than allowing them to radiate their energy away from the PCB.
Safety Certified Capacitors are designed for surge or lightning immunity in modem facsimile and other equipment. The capacitors of KGK are class X1/Y2 compliant, and the capacitors of KGH are class X2 compliant, respectively. The green type capacitors in KGK/KGH are manufactured by using environmentally friendly materials without lead or cadmium.
Class-X capacitors, positioned between line and neutral, help manage overvoltage by directing unwanted surges safely across the line, thereby protecting sensitive circuitry. Class-Y capacitors, used between line and ground, are crafted to fail open, reducing the risk of electrical shock and enhancing safety in case of high transient voltages.
Safety capacitors (both the type X and type Y) work by supplying an instantaneous high-capacity current to the device that is connected to the power source. In most cases, the capacitors are used in combination with the overvoltage protection devices or surge protectors whose function is to detect any surge of current in a circuit.

Class X2 Capacitor Safety Capacitors are available at Mouser Electronics. Mouser offers inventory, pricing, & datasheets for Class X2 Capacitor Safety Capacitors.
Those connected from line-to-ground are called “Y capacitors,” also referred to as “line bypass capacitors.” X capacitors are used for differential-mode EMI filtering. Y capacitors are used for common mode EMI filtering bypassing the interference from the wires to ground.
The internal series construction of X2 film safety capacitors helps the device to last longer and maintain capacitance in series impedance or across-the-line applications

Certified Safety Capacitors are vital components for safety-critical across-the-line and line-to-chassis applications. X-class capacitors are used across the line where failure would not lead to an electrical shock.
Certified Safety Capacitors are vital components for safety critical across-the-line and line-to-chassis applications. X-class capacitors are used across the line where failure would not lead to an electrical shock. X-class capacitors are divided into sub-classes by its rated and pulse voltage. See Table 1.
What this means is, Y class capacitors are designed to simply not fail at all, or be self-healing, allowing them to recover from an arc-over event. Basically, the requirements for a class Y capacitor are stricter and higher than
Certified Safety Capacitors are vital components for safety critical across-the-line and line-to-chassis applications. X-class capacitors are used across the line where failure would not lead to an electrical shock. X-class capacitors are divided into sub-classes by its rated and pulse voltage. See Table 1. Table 1.
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.
X and Y safety capacitors filter AC signals and reduce EMI, so they are directly connected to hazardous AC mains voltages and must be certified as "safety capacitors" to ensure safe operation under these conditions. There are various types of safety capacitors used in safety filter circuits.
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.
X-class safety capacitors classification Y-class capacitors are used in “line-to-ground” applications where failure could lead to an electrical shock. It is also divided into sub-classes by their AC voltage and peak surge voltage ratings. See Table 2.
Normally a Class Y safety capacitor is recommended for this, but a Class X safety capacitor could also be used. The idea here is that the connection allows high-frequency noise currents to pass between the grounds as needed rather than allowing them to radiate their energy away from the PCB.
