BLM31KN Automotive EMIFIL® Chip Ferrite Beads

Murata Electronics BLM31KN Automotive EMIFIL^® Chip Ferrite Beads are ideal for power supply circuits that require a high rated current. These beads are suitable for suppressing high-frequency noise over a wide frequency range in power supply circuits, and most are AEC-Q200 qualified. The AEC-Q200 ferrite beads are ideal for automotive applications such as infotainment and powertrain safety. The series includes non-automotive-grade beads, which are suitable for general purpose power supply circuit usage, including industrial, test equipment, factory automation, and networking. Murata Electronics BLM31KN Automotive EMIFIL Chip Ferrite Beads are packaged in a small 1206 case size (3.2mm x 1.2mm x 1.2mm) and achieve a high 6A impedance.
