AI Customer ServiceCertified 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.
As with many safety-critical devices, varying standards and respective classifications are used to indicate the capabilities and threshold of safety capacitors. There are a variety of standards that are used to define safety capacitors such as IEC 60384-14, UL 1414, UL 1283, CAN/CSA C22.2 No.1, and CAN/CSA 384-14.
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. The world’s most trusted PCB design system.
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.
