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 1000 μH
• 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
