Wurth Elektronik Openable Diameter 7.5 mm Ferrite Clamp STAR-TEC Series 74271131

Wurth Elektronik 74271131 Openable Diameter 7.5 mm Ferrite Clamp from the STAR-TEC Series is designed to provide reliable suppression of electromagnetic interference in general applications. Its high-quality NiZn EMC ferrite core material is optimized for operation over a frequency range of 1 MHz to 1 GHz, effectively reducing EMI in cables and wiring assemblies.

This ferrite clamp features an openable housing with a patented STAR-TEC key technology, allowing for secure locking and preventing unauthorized removal. This key system makes it reusable, ideal for test and measurement purposes in EMC labs, enabling quick assembly and disassembly without damage.

The clamp supports fastening of round cables with diameters from 3.5 mm up to 25.0 mm, or multiple turns of cable wound through the ferrite for enhanced EMI suppression. The plastic protective housing meets UL94 V0 flammability classification and can operate within temperatures ranging from -25 °C to +105 °C.

Its compact build includes external dimensions of 24.6 mm depth, 36.4 mm width, and 20.1 mm height, with a single aperture diameter of 7.5 mm. The impedance characteristics are 125 Ω at 25 MHz, 235 Ω at 100 MHz, and 145 Ω at 500 MHz, providing efficient filtering over a broad frequency spectrum.

Suitable for cable diameters from 3.5 mm to 25.0 mm with fast clamping and secure locking. Core material is NiZn EMC ferrite providing effective suppression between 1 MHz and 1 GHz. Openable design allows easy reusability, ideal for testing and measurement in EMC laboratories.

Internal security locking system with patented STAR-TEC key prevents unauthorized removal. Plastic housing classification UL94 V0, operating temperature range from -25 °C to +105 °C. Compact external size for integration in confined electronic assemblies.

High impedance values ensure broad frequency EMI suppression.

This ferrite clamp is commonly used in electronics manufacturing, EMC testing, power and signal cable assemblies and other applications requiring EMI reduction. It supports compliance with REACH and RoHS standards ensuring environmental safety.
