DO5022P 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.)
  • Very high current rating - up to 8.6 Arms, 20 A saturating current!
  • Flat top for reliable surface mounting
  • Robust temperature deflection prevents damage during solder reflow
  • Custom versions available
  • 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 C311

1 When ordering, please specify termination and packaging codes: e.g. DO5022P-105MLD
  Termination: L = RoHS compliant gold over nickel over phos bronze
Special order, added cost: 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 (250 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 using an Agilent/HP 4263B LCR meter or equivalent.
3 For SRF >13 MHz, measured using an Agilent/HP 8753D network analyzer. For SRF<13 MHz, measured using an Agilent/HP 4192A. 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.
See Qualification Standards for complete environmental and test data.
