UP37-IR2

 

Dielectric Strength

Capacitors withstand a DC potential of 130% rated voltage for two (2) minutes without damage or breakdown. Test voltage is applied and discharged through a resistance of 1 ohm per volt minimum, and at 25°C.

 

UP37-CC

 

Dissipation Factor

Polypropylene has an intrinsic dissipation factor of less than 2.1 x 10-4 over the operating temperature range of -55°C to +105°C and frequencies to 1MHz.
