On July 7th, Murata Manufacturing Co., Ltd. will commercialize the 0402 size (1.0×0.5mm) chip ferrite bead BLM15EG_SH1 series for power supply systems for automotive power transmission systems and safety applications. The BLM15EG_SH1 series can support large currents for power lines and high-frequency (near 1 GHz) impedance, making it suitable for noise suppression in a wide frequency range. The product has been mass-produced in February 2017.
Conventional high-frequency characteristics of chip ferrite beads are difficult to support large currents due to internal structure. The BLM15EG_SH1 series revisits the internal structure and seeks to reduce the impedance and support large currents.
It has high-frequency impedance characteristics and good electrical characteristics, and is suitable for high-reliability chip ferrite beads for noise suppression in a wide range of power supply lines for vehicles.
