Vishay Dale

Inductors

Epoxy Conformal Coated, Axial Leaded

FEATURES

•

High performance ferrite core is used in this epoxy conformally

coated choke which allows for inductance values to 1000µH.

•

Axial lead type, small lightweight design.

•

Special magnetic core structure contributes to high Q and

self-resonant frequencies.

•

Treated with epoxy resin coating for humidity resistance to

ensure long life.

•

Heat resistant adhesives.
