Würth Elektronik WE-STAR-TEC Split Ferrite Core, 8.5mm, 241 Ohm, 35g

The Würth Elektronik WE-STAR-TEC Split Ferrite Core is a high-quality electromagnetic interference (EMI) suppression component designed for ease of use and reliable performance. Part of the innovative STAR-TEC series, this snap-on ferrite core features a NiZn (nickel zinc) core material, which is optimised for supplementary interference suppression across a broad frequency range from 1MHz to 1GHz. Its split design allows for simple retrofitting onto existing cables without the need for disconnection.

A standout feature is the user-friendly pre-fixed cable system, which facilitates the cable assembly process and includes cable clamping protection to prevent errors during installation. The core can be opened and refitted at any time using the patented STAR-TEC safety key. This key operates an internal security locking system that prevents the unauthorised removal of the ferrite from the cable, ensuring the integrity of your EMI suppression setup is maintained.

The robust plastic housing is classified to the UL94 V-1.5 flammability standard, offering good fire safety characteristics. It is built to perform reliably in a wide operating temperature range from –25°C to +105°C, making it suitable for demanding industrial environments. With an impedance of 241 ohms and designed for cables with a diameter of 8.5mm, this ferrite core is an effective solution for mitigating high-frequency noise on data, power, and signal lines.

Key Applications

This ferrite core is ideally suited for use in industrial automation systems, test and measurement equipment, and any electronic application where controlling electromagnetic emissions or improving immunity is critical. Its secure locking mechanism makes it perfect for applications where tampering or accidental removal must be prevented.
