The FCM1005KF-241T04 is a 0402 size ferrite bead manufactured by TAITEC and compliant with RoHS standards. It has a ±25% tolerance on its value of 240 O with a 100 MHz frequency. The bead is used to suppress high frequency noise and radio frequency interference (RFI) between components, such as power converters, and around circuits, such as switching mode power supplies (SMPS). It features high current handling capacity, low DC resistance, and low insertion loss, making it suitable for use in high current applications.
