Document 625-1 High-Current Air Core Inductors The use of heavy gauge wire allows these parts to have the lowest DCR and highest current ratings of our air- core inductors. They offer Q values of 100 or greater from 150 MHz to 1 GHz. Request free evaluation samples by contacting Coilcraft or visiting www.coilcraft.com.

In an effort to simplify our part 5.26 mm pocket depth numbering system, Coilcraft is eliminating the need PCB washing Tested to MIL-STD-202 Method 215 plus an additional for multiple packaging codes. When ordering, simply aqueous wash. See Doc787 PCB Washing.pdf. change the last letter of your part number from B to C. D = 13 machine-ready reel. EIA-481 embossed plastic tape (GA3092 - GA3095 1000 parts per full reel WA3096, WA3097 1500 parts per full reel). Factory order only, not stocked. 2. L and Q measured at 150 MHz, 0.1 Vrms, 0 A using an Agilent/HP 4291A impedance analyzer with an Agilent/HP 16193A test fixture. 3. SRF measured using an Agilent/HP 8722ES network analyzer and a Coilcraft SMD-D test fixture. 4. DCR measured using a micro-ohmmeter. 5. Current that causes a 15C temperature rise from 25C ambient.
