Fastron 1812CMF/E Common-Mode Filter Chip Inductors

Fastron 1812CMF/E Common-Mode Filter Chip (CMC) Inductors protect differential signal paths from common-mode disturbances. The inductors feature two coupled windings wound, providing a symmetrical coil. These Fastron CMC inductors target applications in automation, industrial, and automotive. 1812CMF/E is useful in data-line filters, Ethernet networking, CAN-Bus, USB, wideband noise suppression, and EMC circuit protection for incoming radiation and outgoing noise emission.
