Common Mode Filter Chip Inductors

FASTRON adds a Common Mode Filter in package size 1812 to its product portfolio. The 1812CMF has two parallel copper windings wound providing a symmetric coil.

A ferrite plate on top of the ferrite core works as a magnetic shield and allows for pick and place assembly. The tin pad metallization provides excellent solderability.

Applications

The 1812CMF’s general purpose is filtering fast signals path at high frequencies. The Common Mode Choke is designed to provide highest quality

for the most stringent applications e.g. automotive, industrial and automation. The part could be used in data-line filters, Ethernet networking,

CAN-Bus, USB, wideband noise suppression and EMC circuit protection for incoming radiation and outgoing noise emission.
