Termination Finish Options (Part # Code)
Gold over Nickel (Standard): As shown.
Tin/Lead over Nickel: Add suffix “S” to part # (e.g.,
103-102KS).
Parts listed above are QPL/MIL qualified
Mil type “A:” Gold over Nickel (Standard)
Mil type “B” or “F:” Tin/Lead (solder) over Nickel.
RoHS type: Order 103R - XXXKS
Optional Tolerances: J = 5% H = 3% G = 2% F = 1%
*Complete part # must include series # PLUS the dash #
Mechanical Configuration
Units are epoxy encapsulated.
For further surface finish information,
refer to TECHNICAL section of this catalog.
Contact areas for reflow soldering are gold plated per
MIL-G-45204 Type 1-Grade A. Internal connections
are thermal compression bonded.
Notes 1) Designed specifically for reflow soldering and other high
temperature processes with metalized edges to exhibit solder
fillet. 2) Self Resonant Frequency (SRF) Values above 250 MHz
are calculated and for reference only. 3) (**) - MS slash numbers
available in 20% (Suffix “M”) and 10% (Suffix “K”) tolerances.
Packaging Tape & reel (8mm): 7" reel, 2000 pieces
max.; 13" reel, 8000 pieces max.
Made In the U.S.A.
