BLM Chip Ferrite Beads

Murata BLM Chip Ferrite Beads are designed for power supply circuits that require high rated current. The ferrites are suitable for suppressing high-frequency noise over a wide frequency range in power supply circuits. Murata BLM EMIFIL Chip Ferrite Beads offer AEC-Q200 certified products for automotive applications such as infotainment and powertrain safety applications. Non-automotive grade ferrites are ideal for general purpose power supply circuits, including industrial, factory automation, and networking.
