DO3308P Series
Surface Mount Power Inductors

New RoHS part numbers are shown. The products were always compliant; only the part numbers changed. Added characters indicate tolerance, RoHS compliance, and packaging. (Old data sheet can be viewed here.)

Recommended for use with SIMPLE SWITCHER^® switching regulators
Very low profile - less than 0.118" (3 mm) high!
High energy storage and very low resistance
Flat top for reliable surface mounting
Robust temperature deflection prevents damage during solder reflow
RoHS-compliant 260°C compatible. Gold over nickel over phos bronze terminations
COTS Plus tin-silver-copper and tin-lead terminations available.
Samples of all values are available in Coilcraft Designer's Kit C309

* L1 when used with LM258X Series of SIMPLE SWITCHER® switching regulators
1	When ordering, please specify termination and packaging codes: e.g. DO3308P-334MLD
	Termination:	L = Gold over nickel over phos-bronze Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37).
	Packaging:	D = 13" reel, machine-ready EIA-481 embossed plastic tape. Factory order only, not stocked (1000 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.
3	Isat: DC current at which the inductance drops 10% (typ) from its value without current. Details
4	Irms: Current that causes a 40°C temperature rise from 25°C ambient. Details
5	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 Packaging: –55°C to +80°C
7	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.
8	Electrical specifications at 25°C.
See Qualification Standards for complete environmental and test data.
Refer to Soldering Coilcraft Components before soldering.
