1	When ordering, please specify termination and packaging codes: e.g. DO1608C-105MLC
	Termination:	L = Gold over nickel over moly-manganese terminations Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37).
	Tolerance:	K = 10%, M = 20% (Table shows stock tolerances in bold.)
	Packaging:	C = 7" machine-ready reel EIA-481 embossed plastic tape (750 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 C instead. D = 13" reel, machine-ready EIA-481 embossed plastic tape. Factory order only, not stocked (2500 per full reel).

2	Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/HP 4263B LCR meter or equivalent.
3	Tolerances in bold are stocked for immediate shipment
4	DCR measured at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
5	Isat: DC current at which the inductance drops 10% (typ) from its value without current. Details
6	Irms: Current that causes the specified temperature rise from 25°C ambient. Details
7	Ambient temperature range:	–40°C to +85°C with Irms current. +85°C to +125°C with derated current Derating curve
6	Storage temperature range:	Component: –40°C to +125°C Tape and reel packaging: –40°C to +80°C
8	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.
9	Electrical specifications at 25°C.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested with pure water or alcohol only. Other solvents.
