Power Inductors (SMD): Multilayer Type Power Inductors

Multilayer Type Power Inductors design engineers Panasonic
Power Inductors (Multilayer type) ELG-TEA

Panasonic multi-layer power inductors feature a small 0805 case size and excellent DC current bias characteristics, driven by Panasonic’s proprietary laminating process technology.

MLPI is miniaturized and corresponding to large current, therefore it contributes to space and cost reduction of DC/DC Power supply circuit

We have realized large-current MLPI by introducing ferrite green sheet material (our original technology) and improving multilayer technology. Magnetic layers between coils are thinner than it used to be.
