Model IRF-24
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.
