RFC0810B Series

Power Inductors

RoHS compliant halogen free AEC-Q flag
For values <33 µH, please consider the RFB0810 series. The RFB0810 is the same size and has the same PC board layout.
Coilcraft RFC0810B Series unshielded, radial-leaded inductors are a low-cost option for general-purpose applications.  High-reliability extended temperature versions of many series are available for space, military, and other critical applications.  RFC0810B Series are cost-reduced higher inductance versions.
  • Open magnetic path
  • Rugged through-hole (TH) mount construction
  • High saturation current ratings
  • Ferrite core gives flat L vs I curve
  • AEC-Q200 Grade 3 (−40°C to +85°C)

Notes
  1. When ordering, please specify lead length and termination codes: e.g. RFC0810B-183KE
  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.
