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
