EFP SERIES

High Current Multilayer Chip Beads

EFP SERIES

Features

These high current Beads do not require wiring, with minimum capacity and lower DC resistance characteristic, they are designed to eliminate EMI for electrical equipment power line use.
Available in high current which up to 6A.
Closed magnetic circuit avoids crosstalk, suitable for high density PCB.
Excellent for high current applications such as power supplies, Industrial equipment, OA products, communication products, etc..
