DO3308P Series
Surface Mount Power Inductors

  • 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

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 DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
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. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves.
5 Ambient temperature range: −40°C to +85°C with Irms current. Derating curve
6 Storage temperature range: Component: −40°C to +125°C
Tape and reel packaging: −40°C to +80°C
7 Maximum part temperature: +125°C (Ambient + temperature rise) Derating curve
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.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
