High-frequency air core inductors

21 August 2013 Passive Components

Coilcraft’s new 1111SQ Series high-performance, square air core inductors offer high Q factors – up to 200 at 400 MHz – and inductance values from 27 nH to 47 nH. They are available in seven models with footprints from just 2,67 x 2,67 mm.

The spring was engineered to have a unique square shape that has been optimised for coplanarity, resulting in a flat top and bottom for reliable pick and place operation and mechanical stability on the printed circuit board. Solder-coated leads also ensure excellent solderability.

The inductors offer current ratings to 5,5 A, making them suitable for use as chokes in high-current RF power amplifiers for cellular towers and high-power radar. Their combination of performance, inductance values and tolerances as tight as 2% also make them ideal components in DOCSIS (Data Over Cable Service Interface Specification) applications such as set-top boxes and cable modems.
