Safety capacitors are also called EMI / RFI suppression capacitors, AC line filter safety capacitors, or X- and Y-rated capacitors. X and Y capacitors not only keep radio frequency noise generated by the device local to that device, but also protect the device from mains noise and high voltage surges.
All safety capacitors are approved according to IEC 60384-14.4, UL, and CQC, while all series are compliant with RoHS and the REACH regulations. Vishay’s line of X1 / Y2 and X2 surface-mount safety capacitors offers devices for operating voltages up to 250 VAC. As surface-mount devices, the capacitors simplify circuit board assembly.
Of note is a 1 nF capacitance value offered in the C0G (NP0) material, which offers a consistent capacitance with respect to both temperature and applied voltage. Surface-mount safety capacitors are available in commercial and Vishay Automotive Grades (AEC-Q200 qualified), with PPAP data upon request.
The so-called self-healing capability is not the same as fail safe system stability. 4. Most internal protective devices can inter-rupt the voltage only within the capacitor. They are not fuses in the classical sense such as cable or device fuses which inter-rupt the voltage upstream from the faulty system component. 5.
Vishay’s line of X1 / Y2 and X2 surface-mount safety capacitors offers devices for operating voltages up to 250 VAC. As surface-mount devices, the capacitors simplify circuit board assembly. The components are supplied in tape and reel packages and are picked and placed the same as all other surface-mount components.
To be clear, you should select your Class-X and Class-Y capacitors according to your design's purpose and requirements. Whereas X2 and Y2 caps are appropriate for household applications, X1 and Y1 safety capacitors are used in industrial settings.
