Meeting Your Needs
The LLM2520 Series is a ferrite core wirewound surface mount
chip inductor which conforms to the EIA standard 1008 foot-
print. Its proprietary welded termination architecture offers su-
perior reliability and high heat-resistance for flow and reflow
soldering capability. It is an economical choice for general signal
conditioning, RF or IF filtering applications, or as matching elements.
