BL01RN1A1D2B (MURATA)

The BL01 series from Murata are axial leaded EMIFIL ferrite beads inductor. These inductor type EMI suppression filters are designed to operate from several MHz to several GHz. They are widely used as general purpose noise suppression components to cope with relatively minor noise issues. EMIFIL Inductor type filters behave as inductors with small inductance at low frequencies, while they produce a resistance dominated impedance at high frequencies. When these ferrite beads are serially inserted into a noise transmission path, the resistance component absorbs and prevents the transmission of noise.
