DC1012 Series
Power Inductors

  • Ideal for applications requiring small size, cost effective power inductors
  • Ideal for use as DC-DC converter boost or buck inductors and as output ripple filter chokes
  • Vertical style helps reduce power supply size
  • AEC-Q200 Grade 3 (−40°C to +85°C)
  • RoHS-compliant. Tin-silver over tin over copper over steel terminations
  • Samples of all values are available in Coilcraft Designer's Kit P410

1 When ordering, please specify termination code: e.g. DC1012-334L
  Termination: L = RoHS compliant tin-silver (96.5/3.5) over tin over copper over steel.
Special order: S = non-RoHS tin-lead (63/37).
2 Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc.
3 DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
4 Isat: DC current at 25°C that causes the specified inductance drop from its value without current.
Temperature derating curves.
5 Irms: Current that causes the speicified 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
Packaging trays or tape: −40°C to +80°C
8 Maximum part temperature: +125°C (Ambient + temperature rise)
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.
