When ordering, please specify termination and packaging code: e.g. 0402HL-821XJRW

Termination:

R = RoHS compliant matte tin over nickel over silver-platinum-glass frit
Special order, added cost: Q = RoHS tin-silver-copper (95.5/4/0.5) or
P = non-RoHS tin-lead (63/37).

Packaging:

W = 7" machine-ready reel
EIA RS-481 embossed plastic tape (2000 parts per full reel).
U = Less than full reel
In tape, but not machine-ready. To have a leader and trailer added ($25 charge), use code letter W instead.

2	Inductance measured at 0.1 Vrms, 25 MHz using a Coilcraft SMD-A fixture in an Agilent/HP 4287A impedance analyzer or equivalent with Coilcraft-provided correlation pieces.
3	Q measured using a Coilcraft SMD-F fixture in an Agilent/HP 4287A impedance analyzer or equivalent.
4	SRF measured using an Agilent/HP 8753D network analyzer with Coilcraft SMD‑D test fixture. Details
5	DCR measured at 25°C on Cambridge Technology Micro-ohmmeter or equivalent. For other operating temperatures, use this DCR at Temperature calculator.
6	Irms: Current that causes a 15°C temperature rise from 25°C ambient. Details
7	Ambient temperature range:	–40°C to +125°C with Irms current. +125°C to +140°C with derated current. Derating curve
8	Storage temperature range:	Component: –40°C to +140°C Tape and reel packaging: –40°C to +80°C
9	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.
10	Electrical specifications at 25°C.
11	Temperature coefficient of inductance (TCL): +25 to +150 ppm/°C.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested with pure water or alcohol only. Other solvents.
