Würth Elektronik WE-STAR-TEC Cable Ferrites PIO | DigiKey

The Würth Elektronik WE-STAR-TEC and STAR-TEC LFS series of snap ferrites cater to a range of cable diameters from 3.5 mm to 25 mm, with distinct core materials tailored for different frequency suppression needs. The WE-STAR-TEC series utilizes NiZn cores to target interference in the 1 MHz to 1 GHz range, ideal for additional EMI suppression, while the STAR-TEC LFS series employs MnZn cores focused on the 300 kHz to 30 MHz range, making it suitable for low-frequency applications such as electronic ballasts in lighting. Both series boasts user-friendly features like a prefixing cable system for easier assembly, cable clamping protection, and a unique internal security locking system controlled by a patented STAR-TEC key, ensuring the ferrites can be securely attached and only removed with authorization, thereby enhancing their suitability for repeated use in EMC labs and other settings requiring secure, adaptable frequency suppression solutions.
