(2) Typical Resistance change, the maximum is the same as
MIL-PRF-55342. Test methods are per MIL-PRF-55342.
Solderability: Solder coating compatible with Sn60, 62 or
63 solders, provides good wetting with all types of solder
attachment. All product is tested IAW Mil-Std-202,
method 208, including 8 hour steam aging.

* PRODUCT LEVELS
All product levels are based on the same design as our "R" level failure rate Established
Reliability part. Level C is a Non-Established Reliability part requiring no group A, B or C
testing. Established Reliability (failure rates based on life testing) product levels M,P, and R
are subject to group A, B and C testing per MIL-PRF-55342. Space product level T requires
group A and B tests including 100% power conditioning.
OPTIONS
Termination type wraparound style (pretinned with a Ni barrier),
and type W (wire bondable) are available. Also available in
thick film MIL-PRF-55342 characteristic K & M. SOTA offers a
full line of component parts in the 0603 size including Standard
Grade, High-Reliability (customer specified testing), and zero-
ohm jumpers.
