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
  • AEC-Q200 Grade 3 (−40°C to +85°C)
  • RoHS-compliant. 260°C compatible. Tin-silver-copper 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
  • Need parts for space, military or other critical applications? See Coilcraft CPS 563PKA series.

1 When ordering, please specify tolerance, termination and packaging codes: e.g. DO3316H-472MLD
  Tolerance: M = 20%, K = 10% (Table above shows stock tolerances in bold.)
  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 Tolerances in bold are stocked for immediate shipment.
4 DCR measured at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
5 SRF measured using an Agilent/HP 8753D network analyzer. Details
6 Isat: DC current at 25°C that causes a 10% (typ) inductance drop from its value without current.
Temperature derating curves.
7 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.
8 Ambient temperature range: −40°C to +85°C with Irms current.
9 Storage temperature range: Component: −40°C to +125°C
Tape and reel packaging: −40°C to +80°C
10 Maximum part temperature: +125°C (Ambient + temperature rise)
11 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.
12 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.
