Datasheet

COO (Country of Origin):: HU

Epcos B82721A Series Common Mode Choke

Current-compensated ring core double chokes with a ferrite core in flame retardant potting and case to (UL94V-0)

High resonance frequency by virtue of the unique winding technique used

Applications include switch-mode power supplies for computers, televisions and other sensitive electronic equipment. Additionally the B82721/2/3/4/5A ranges of chokes are suitable for electronic ballasts in lamps, and the B82725J range of chokes is ideally suited for washing machines and chargers.

Low profile horizontal (-A/-B) versions

Vertical (-J/-K) versions save PCB space

Note

The stated Rated Current I_R is referenced to 50Hz @ T_A 40°C
The stated Rated Inductance L_R is per Coil @ 20°C
