Document 107-1 Mini SpringTM Air Core Inductors These surface mount air core "spring" inductors provide extremely high Q over a wide frequency range. They're jacketed with a high temperature material that ensures mechanical stability and very tight tolerance. It also forms a flat top, making them suitable for automatic placement and reflow or vapor phase processing. Solder coated leads ensure reliable soldering. Coilcraft Mini SpringTM inductors are available in standard EIA tape and reel packaging: 12 mm for size A, and 16 mm for size B parts. Coilcraft Designer's Kit C102 contains samples of all 5% inductance tolerance parts. Kits with 2% tolerance are also available. To order, contact Coilcraft or visit http://order.coilcraft.com.
