STAR-TEC Snap Ferrites with Safety Key Technology

Würth Elektronik STAR-TEC Snap Ferrites with Safety Key Technology feature both the WE-STAR-TEC and WE-STAR-TEC LFS series. The STAR-TEC ferrites utilize a NiZn core for supplementary interference suppression in the 1MHz to 1GHz range. The STAR-TEC LFS series utilizes an MnZn core for a low-frequency suppression range from 300kHz to 20MHz. Both STAR-TEC snap ferrite series are designed to be user-friendly. Würth Elektronik STAR-TEC and STAR-TEC LFS Snap Ferrites with Safety Key Technology operate in the -25°C to +105°C temperature range.
