RF INDUCTORS
Current Rating at 90°C Ambient
35°C Rise
Operating Temperature Range
–55°C to +125°C
Maximum Power Dissipation at 90°C
0.105 W
Core Material
Powdered iron core for improved
temperature stability.
Mechanical Configuration
Units are epoxy
encapsulated. Contact area for reflow soldering are
gold plated per MIL-G-45204 Type 1 Grade A.
Internal connections are thermal compression
bonded.
Termination Finish Options
Standard: Gold over Nickel.
For Tin/Lead over Nickel: Add suffix “S” to part
number and allow an additional .010 inch for
maximum height. For RoHS, order 3090R - XXXKS.
Packaging
Tape & reel (8mm): 7" reel, 2000 pieces
max.; 13" reel, 8000 pieces max.
MIL-PRF-83446 (Reference)
for testing methods
only.
Made in the U.S.A.
Optional Tolerances:
J = 5% H = 3% G = 2% F = 1%
*Complete part # must include series # PLUS the dash #
For further surface finish information,
refer to TECHNICAL section of this catalog.
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 250 MHz
and above are calculated and for reference only.
