6 FAQs about [X-type y-type capacitors]
What are x & y safety capacitors?
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.
What are Class X and Class Y capacitors?
Class-X and Class-Y capacitors help to minimize the generation of EMI/RFI and the negative effects associated with received EMI/RFI. In order for these capacitors to perform their EMI/RFI filtering tasks, they are directly connected to the AC power input, that is, the AC “line” and the AC “neutral” (see Figure 2 below).
What are X & Y capacitors?
The designations X-capacitor and Y-capacitor refer to the role and placement of these capacitors in the line-facing input of a circuit. If all your design is at lower AC voltages — typically below 50 volts — or for DC-powered designs, these capacitors are unneeded.
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.
How do I choose a Class X & Y safety capacitor?
