1 When ordering, please specify packaging code: e.g. SBU9-6011R0LC
Packaging: D = 13" machine-ready reel
EIA-481 embossed plastic tape 350 parts per full reel).
B = Less than full reel
In tape, but not machine-ready. To have a leader and trailer added ($25 charge), use code letter D instead.
2 Inductance tested at 1 kHz, 1 Vrms, and it is measured on Agilent/HP 4263B LCR meter or equivalent.
3 Irms: Current that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
4 DCR is for each winding, measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
5 Interwinding isolation (hipot) tested for one minute.
5 Operating temperature range −40°C to +125°C Details
6 Electrical specifications at 25°C.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
