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

N = Silver-nickel-gold

S = Solder coated final with a minimum of 4 percent lead

T = Silver

U = Base metallization-barrier metal-solder coated

(tin/lead alloy, with a minimum of 4 percent lead)

W = Base metallization-barrier metal-tinned

(tin or tin/lead alloy)

Y = Base metallization-barrier metal-tin (100 percent)

Z = Base metallization-barrier metal-tinned

(tin/lead alloy, with a minimum of 4 percent lead)

*See MIL-PRF-55681 Specification for more details

Failure Rate Level:

M = 1.0%, P = .1%, R = .01%,

S = .001%

Packaging: Bulk is standard packaging. Tape and reel per RS481 is

available upon request.
