“ARCING”, “SPARKING”, and “TRANSIENTS” often cause premature failures in relays, switches, thyristors, TRIACs, contactors, and related products. QUENCHARC® extends operating life when properly selected and applied. Construction: Metallized polyester in series with a carbon composition resistor. Case: Coated with a flame retardant epoxy. Dielectric Withstand: Units shall withstand a DC potential of 1.6 times the DC voltage rating. Testing conducted at +25°C. Test Method and Performance. DC Life Test: Units shall withstand a test potential of 125% of the rated voltage for a period of 500 hours at 85°C. A failure shall consist of capacitance change >5% or a DF greater than original limits. Long Term Stability: The capacitance shall not change more than 2% when stored at ambient temperature and humidity for a period of two years or less.
