Würth Elektronik WE-STAR-TEC 6mm Split Ferrite Core, 321 Ohm

The Würth Elektronik WE-STAR-TEC Split Ferrite Core is a premium interference suppression component designed to clamp around cables, effectively filtering out high-frequency electromagnetic noise. It features a robust plastic housing with a convenient pre-fixed cable system that simplifies installation and protects the cable from damage during clamping.

At the heart of this component is a high-quality NiZn (nickel zinc) ferrite core, engineered specifically for supplementary interference suppression across a wide frequency range from 1MHz to 1GHz. This makes it an excellent solution for mitigating electromagnetic interference (EMI) in a variety of electronic and electrical applications. A key innovation is the patented internal security locking system, which requires a dedicated STAR-TEC key to open or remove the ferrite from the cable, preventing unauthorised tampering or accidental dislodgement.

The product is built for reliability in demanding environments, with a plastic housing classified to the UL94 V15 flammability standard. It can operate effectively across a broad temperature range from –25°C to +105°C, ensuring stable performance. Its split-core design allows for easy retrofitting onto existing cables without the need to disconnect them, offering great flexibility for both installation and subsequent system modifications.
