pF, F ± 1%, J ± 5%, K ± 10%,
M ± 20%
Termination Finish:
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%
Not RoHS Compliant
