Description
SCI-1021-000 — Threaded Case EMI Filter (L-Circuit, Low Profile)
A low-profile, threaded-case EMI filter from Spectrum Control’s 0.375″ L-circuit series. It uses an L-C (LB) filter circuit to deliver broadband EMI suppression from 30 kHz through 1 GHz on signal and DC power lines, and mounts via a 1/4-28 UNF-2A threaded bushing. This part number is resin sealed (non-hermetic).
