DO1813H Series High Current
Surface Mount Power Inductors

  • Small high current inductor - only 0.24" × 0.35" × 0.197" high
  • Very high current ratings - up to 10 Arms; 14.0 A saturating current
  • 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
  • AEC-Q200 Grade 3 (−40°C to +85°C)
  • Custom versions available
  • RoHS-compliant. 260°C compatible. Tin-silver over copper terminations
  • COTS Plus tin-silver-copper and tin-lead terminations available
  • Samples of all values are available in Coilcraft Designer's Kit C331

1 When ordering, please specify termination and packaging codes: e.g. DO1813H-473MLD
  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 (1000 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, 0.25 Vrms using an Agilent/HP 4263B LCR meter or equivalent.
3 DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
4 Isat: DC current at which the inductance drops 30% (typ) from its value without current.
Temperature derating curves
5 Irms: Current that causes a 40°C temperature rise from 25°C ambient.This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves
6 Ambient temperature range: −40°C to +85°C with Irms current. Derating curves
7 Storage temperature range: Component: −40°C to +125°C
Tape and reel packaging: −40°C to +80°C
8 Maximum part temperature: +125°C (Ambient + temperature rise) Derating curves
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.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
