1 When ordering, please specify packaging code: e.g. CU8838-ALD


D = 13" machine-ready reel
EIA-481 embossed plastic tape (500 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 100 kHz, 0.1 Vrms using a Coilcraft SMD-A fixture and an Agilent/HP 4284A LCR meter.
3 DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
4 SRF measured using an Agilent/HP4291A impedance analyzer or equivalent and a Coilcraft16193 fixture.
5 Isat: DC current at which the inductance drops the specified amount from its value without current. Details
6 Irms: Current that causes specified temperature rise from 25°C ambient. Details
7 Ambient temperature range: −40°C to +85°C with (40°C) Irms current.
8 Maximum part temperature: The part may be operated without damage as long its temperature (ambient + self-heating) does not exceed +125°C
9 Storage temperature range: Component: −40°C to +125°C
Tape and reel packaging: −40°C to +80°C
10 Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
11 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..
