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.
STANDARD ELECTRICAL SPECIFICATIONS
• Special magnetic core structure contributes to high Q and
self-resonant frequencies.
