Air-core RF inductors

30 March 2022 Passive Components

The 111SQ from Coilcraft is a square air-core inductor series with a remarkably high quality factor of up to 200 at 400 MHz. The parts come in a range of inductances from 27 µH to 47 µH and have a self-resonant frequency (SRF) between 2,2 GHz and 2,6 GHz.

The inductors have solder-coated leads to ensure optimal solderability and a flat top and bottom for easy placement via pick-and-place machines. They are RoHS-compliant, halogen-free and operate at temperatures up to 260°C.
