Saturation current rating up to 2.7 Amps; Low DC resistance for greater efficiency
Specified by National Semiconductor for their LM2830 Buck Converter
21 inductance values from 1.0 to 100 µH
RoHS-compliant. 260°C compatible. Matte tin over nickel over silver terminations
COTS Plus tin-silver-copper and tin-lead terminations available
Samples of all values are available in Coilcraft Designer's Kit C386

1	When ordering, please specify termination and packaging codes: e.g. ME3220-104KLC
	Termination:	L = RoHS compliant matte tin over nickel over silver Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37).
	Packaging:	C = 7" machine-ready reel EIA-481 embossed plastic tape (2000 parts per full reel). B = Less than full reel In tape, 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 (7000 parts per full reel).

2	Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using Coilcraft SMD-A fixture in Agilent/HP 4263B impedance analyzer.
3	DCR measured on a micro-ohmmeter and Coilcraft CCF858 test fixture.
4	SRF measured using Agilent/HP 8753D network analyzer and a Coilcraft SMD-D fixture. Details
5	Isat: DC current at which the inductance drops 30% max from its value without current. Details
6	Irms: Current that causes a 40°C 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
8	Storage temperature range:	Component: –40°C to +125°C T&R 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.
Refer to Soldering Coilcraft Components before soldering.
