Würth Elektronik Split Ferrite Core, 7.5mm, 246 Ohm

The Würth Elektronik WE-STAR-TEC split ferrite core provides essential supplementary interference suppression for electronic systems. This component is part of the WE-STAR-TEC series, designed for cables with a diameter of 7.5mm. It features a high-performance NiZn core, specifically engineered for effective electromagnetic interference (EMI) suppression in the frequency range of 1MHz to 1GHz, making it ideal for tackling higher frequency noise.

A key advantage of this ferrite core is its exceptional user-friendliness. It incorporates a prefixed cable system, which simplifies and accelerates the installation process onto cables. This system, combined with integrated cable clamping protection, helps prevent errors and ensures a secure fit. The patented security locking mechanism allows the core to be opened and refitted at any time, but requires the dedicated STAR-TEC key (sold separately). This internal locking system effectively prevents unauthorised removal of the core from the cable, offering an added layer of security in sensitive applications.

Constructed with a robust plastic housing classified to UL94 V-1.5, the core is both durable and flame-retardant. It operates reliably across a wide temperature range from –25°C to +105°C, ensuring stable performance in demanding industrial environments. The 7.5mm size offers a versatile solution for a broad range of cable management and EMI suppression tasks.

This component is particularly well-suited for use in industrial automation, test and measurement equipment, data communication systems, and any electronic application where controlling electromagnetic emissions and improving signal integrity is critical. Its design focuses on reliability, ease of use, and effective high-frequency noise suppression.
