MILITARY DESIGNATION PER MIL-PRF-55681
Part Number Example
(example) CDR31 BP 101 B K S M
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 gures 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 nal 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/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 Specication 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.
NOTE: Contact factory for availability of Termination and Tolerance Options
for Specic Part Numbers.
