Temperature Characteristic at Rated Voltage

Capacitance Tolerance

Rated Voltage

BP = ± 30 ppm/°C

C = ± 0.25 %

B =  50 V

BX = + 15%, -25%

D = ± 0.50 %

C = 100 V

BR = + 15%, -40%

J = ± 5.0 %

K = ± 10.0 % 

Capacitor Values:
Capacitance values in picofarads are contained in the following listing. When ordering, the first two digits represent significant figures and the last digit specifies the number of zeroes to follow. For example 101 indicates 100 pF and 102 indicates 1000 pF. The letter "R" shall be used to indicate a decimal point when required. For example 1R0 indicates 1.0 pF.
