Helical Filters
Helical Filters are designed to remove unwanted frequencies from a circuit. Items in this family use a spirally wrapped wire around a central core. Their center frequencies range from 216 MHz to 1.015 GHz with a bandwidth of 2.6 to 25 MHz, and an insertion loss of 2.5 to 6 dB.
Sourcing Central Technologies Helical Filters: in-stock lines for quick ship, BOM matching for multi-line builds, and original-channel screening — not keyword stuffing.
