Square Air Core High Inductance RF Inductors

Coilcraft Square Air Core High Inductance RF Inductors feature excellent Q factors of up to 230 at 400MHz, with current handling up to 5.7A. These higher inductance variants offer values ranging from 47nH to 500nH. Each value is available at 2% and 5% tolerance in 7" machine-ready reels or less-than-full-reel packaging. The halogen-free RF inductors use solder-coated leads for reliable soldering while having an ambient temperature rating from -40°C to +125°C with Irms current. Coilcraft square air core high inductance RF inductors use a flat top and bottom design for reliable pick and place and mechanical stability.
