Current Rating at 90°C Ambient 35°C Rise
Operating Temperature –55°C to +125°C
Maximum Power Dissipation at 90°C 0.155 W
Termination Standard: Tin/Lead Sn63
Inductance Tolerance Desired tolerance is specified by
substituting alpha characters in the part number: H=3%,
J=5%, K=10%, and M=20%. Standard series tolerance is
±10%.
Mechanical Configuration Units are epoxy
encapsulated. Contact area for reflow are solder coated.
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 260 MHz and above are calculated and for
reference only.
Packaging Tape & reel (12mm): 7" reel, 650 pieces max.;
13"reel, 2500 pieces max.
