Cable ferrites (ferrite clamps, ferrite rings) are slipped over cables and wires to suppress high-frequency conducted and radiated EMI — a common and cost-effective way to reduce EMI in USB cables, HDMI cables, Ethernet cables, power cords, and signal cables for consumer electronics, industrial equipment, and automotive wiring. Our cable ferrite inventory covers split-core and one-piece snap-on ferrites, clamp-on rings, and wire-wound ferrite sleeves from Fair-Rite, Laird (Steward), TDK, Murata, and Bourns — with impedance values from 25Ω to 600Ω at 100MHz, inner diameters from 3mm to 25mm, and frequency ranges from 1MHz to 1GHz.
Specific cable ferrite configurations for high-speed USB 3.x, HDMI 2.1, and automotive CAN/LIN cables with specific impedance requirements face persistent allocation. Welllinkchips stocks common ferrite cable types and can source discontinued or custom-dimensioned ferrites for legacy equipment repair.
