DO3316H Series High Current
Surface Mount Power Inductors

• Very high current ratings - up to 17 Arms; 28 Asat
• Low profile and small footprint - only 0.51" x 0.37" x 0.25" high
• Exceptionally low DC resistance thanks to the use of heavier gauge wire
• Flat top and self-leaded design for reliable surface mounting
• Robust temperature deflection prevents damage during solder reflow
• RoHS-compliant. 260°C compatible. Tin-silver over copper terminations.
• COTS Plus tin-silver-copper and tin-lead terminations available
• Custom versions available
• Samples of all values are available in Coilcraft Designer's Kit C326

1	When ordering, please specify termination and packaging codes: e.g. DO3316H-472MLD
	Termination:	L = RoHS compliant tin-silver (96.5/3.5) over copper. Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) over copper or S = non-RoHS tin-lead (63/37) over copper.
	Packaging:	D = 13" reel, machine-ready  EIA-481 embossed plastic tape (750 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 D instead.

2	Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4263B LCR meter or equivalent.
3	SRF measured using an Agilent/HP 8753D network analyzer. Details
4	Isat: DC current at which the inductance drops 10% (typ) from its value without current. Details
5	Irms: Current that causes a 40°C temperature rise from 25°C ambient. Details
6	Ambient temperature range:	–40°C to +85°C with Irms current. +85°C to +125°C with derated current Derating curve
7	Storage temperature range:	Component: –40°C to +125°C Packaging: –55°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.
