Square Air Core RF Inductors

Coilcraft Square Air Core RF Inductors feature solder-coated leads, excellent Q factors, and cover inductance values ranging from 5.5nH to 500nH. These RF inductors use a flat top and bottom design for reliable pick and place as well as added mechanical stability. Coilcraft square air core RF inductors include lower and higher inductance models. Sample kits are available, containing 10x each of all parts with 5% tolerance.
