FEATURES
High performance ferrite core is used in this epoxy conformally
coated choke which allows for inductance values to 1000
μ
H.
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.
