There is most risk of vibration damage to capacitors in applications where high μF values are used where the parts are physically large, often with many paralleled. Examples would be in DC-link connections in inverters or motor controllers or output filters in high power AC-DC and DC-DC converters.
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.
Even better, the life expectancy increases by an order of magnitude (ten times) for every 20°C the capacitor’s operating temperature decreases. What Makes Solid Polymer Capacitors Good For Vibration? KEMET’s A768 series of solid polymer capacitors are specially designed to be resistant to vibration forces up to 30G.
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.
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.
Vibration resistance is also greatly enhanced by the Panasonic anti-vibration features along with the reduced height, volume and weight. Applications, where vibration resistance is critical, are becoming more common and manufacturer Panasonic is responding with vibration-proof components in their capacitor ranges.
