EPCOS, B82789, 1812 (4532M) SMD Common Mode Choke with a Ferrite Core, 51 μH -30% Wire-Wound 250mA Idc

Current compensated double choke with ferrite I core, EIA 1812
Bifilar winding (B82789C...)
B82789C versions have a bifilar winding suitable for suppression of asymmetric interference
Sector winding (B82789S...)
B82789S versions have a sector winding suitable for suppression of both asymmetric interference (using LR) and symmetric interference (using LS) and can help to reduce high frequency EMC problems
Applications include automotive (e.g. CAN bus), industrial automation and telecommunications
Flame retardant case to UL 94 V-0
Lead-free tinned terminals
