PFL Inductors Coilcraft PFL Inductors offer the current handling of much larger inductors, making them ideal for applications requiring ultra-small inductors that can handle the significant current. These devices feature magnetic shielding for high-density mounting and are RoHS compliant and halogen free. They are a cost-effective combination of size and performance. Coilcraft PFL Inductors come in a wide range of footprints and heights to fit any application.
