describe the state of technology which must as a rule be adhered to in all relevant contracts for goods and services. II. General safety rules Since power capacitors are electrical energy storage devices, they must always be handled with caution.
What is a safety capacitor?
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.
Are Vishay safety capacitors UL compliant?
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.
What are the possible violations of the capacitor specification?
Such violations include excess tempera- ture, overvoltage, incorrect application, incorrect installation, faulty maintenance, mechanical damage, or operation outside the technical limits of the specification. V. Risk factors for the capacitor
What are the risks of a power capacitor failure?
VI. Risks when a fault occurs circuit power. uncontrolled release of this energy. This systems containing several capacitor units due to possible avalanche effects. 2. Power capacitors can actively fail when internal or external protective devices are missing, incorrectly dimensioned or have failed.
Are power capacitors safe?
General safety rules Since power capacitors are electrical energy storage devices, they must always be handled with caution. Even after being turned off for a relatively long period of time, they can still be charged with potentially lethal high voltages.
