Amorphous EMI Core

Description

EMI Cores are for noise suppression and the prevention of of strange wavering in the moderately low recurrence scope of many kHz to several MHz. Including remarkable material innovation, CATECH offers an assorted lineup of ferrite centers that come in various shapes for differing applications. The item run incorporates variations for level links and plates, globules, rings, and multi-opening centers.
CATECH offers a various lineup of EMI cores in various shapes for varying applications. Our items go incorporates variations for level links and in addition plates, sleeve, split, globules, rings, and multi-opening cores.

EMI Ferrite Cores is widely used in INTERCONNECT CABLES, STORAGE DEVICES TAPE/DISK DRIVE, AUDIO-VISUAL EQUIPMENT, TELEVISION SETS, ELECTRIC MOTORS, MEDICAL EQUIPMENT etc. Provide a high performance, cost effective to0l to solve conductive EMI & radiated EMI problems.

As the pioneer of EMI Ferrites products, CATECH China has wide range of EMI core products.
