Safety capacitor classification
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 interference. Class-X and Class-Y capacitors are classified according to: 1. their peak voltage/rated voltage and 2. the peak impulse voltage that they. Subclass X2 and Y2 are the most commonly used safety-certified capacitors. Depending upon your own application and requirements, they are. 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. All safety-certified capacitors should have the proper logo markings/symbols on their casing. See Figure 4 below for an example and see Figure 5 for a definition/description of these logos:.

FAQs about Safety capacitor classification
What is a Certified Safety capacitor?
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.
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.
