Mechanical Configuration Units are epoxy
encapsulated. 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
185 MHz for Series 105 are calculated (reference only).
Packaging Tape & reel (8mm): 7" reel, 2000 pieces
max.; 13" reel, 8000 pieces max.
Made in the U.S.A.
