MIL Style: CDR31, CDR32, CDR33, CDR34, CDR35

Voltage Temperature Limits:

BP = 0 ± 30 ppm/°C without voltage; 0 ± 30 ppm/°C with

rated voltage from -55°C to +125°C

BX = ±15% without voltage; +15 –25% with rated voltage

from -55°C to +125°C

Capacitance: Two digit figures followed by multiplier

(number of zeros to be added) e.g., 101 = 100 pF

Rated Voltage: A = 50V, B = 100V

Capacitance Tolerance: B ± .10 pF, C ± .25 pF, D ± .5

pF, F ± 1%, J ± 5%, K ± 10%,

M ± 20%

Termination Finish:

M = Palladium Silver

U = Base Metallization/Barrier

N = Silver Nickel Gold

Metal/Solder Coated*

S = Solder-coated

W = Base Metallization/Barrier
