RFC0810B Series
Power Inductors

For values <33 µH, please consider the RFB0810 series. The RFB0810 is the same size and has the same PC board layout.
  • Low cost, high efficiency option for choke applications
  • Inductance values from 33 µH to 18 mH
  • Current ratings up to 4.25 Amps
  • AEC-Q200 Grade 3 (−40°C to +85°C)
  • RoHS-compliant. Tin-silver over tin over copper over steel terminations.
  • For higher current ratings or lower DCR, see the RFC1010 Series

1 When ordering, please specify lead length and termination codes: e.g. RFC0810B-183KE
  Lead length A = 3.6 mm ±0.3 mm (special order)
B = 5.0 mm ±0.5 mm
C = 7.0 mm ±0.5 mm (special order)
D = 8.0 mm ±0.5 mm (special order)
E = 10.0 mm ±1.0 mm (special order)
F = 25.0 mm ±1.0 mm, packaged in fanfold tape, 800 parts per box (special order)
  Termination: E = RoHS compliant tin-silver over tin over copper over steel.
Special order, added cost: S = non-RoHS tin-lead (63/37).
2 Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc; measured on an Agilent/HP 4284A LCR meter or equivalent.
3 DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
4 SRF measured using an Agilent/HP 4191A or equivalent. Details
5 Isat: DC current at 25°C that causes the specified inductance drop from its value without current.
Temperature derating curves.
6 Irms: Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves.
7 Ambient temperature range: −40°C to +85°C with (40°C rise) Irms Derating curves
8 Storage temperature range: Component: −40°C to +85°C
Packaging trays or tape: −40°C to +80°C
9 Maximum part temperature: +125°C (Ambient + temperature rise)
10 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.
11 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.
