Leaded Inductors Fastron Leaded Inductors are thru-hole fixed choke coils featuring an inductance range from 0.1µH to 100,000µH. These inductors offer high Q values and come in both ammo pack and tape packaging. The tape packaging offerings include both radial and axial taping. Fastron Leaded Inductors are suitable for use cases such as decoupling, interference suppression, and filtering.
