Available in three performance levels: the RFC0807, RFC0810 and RFC1010 series, Coilcraft’s RFC leaded power inductors offer a low-cost, high-efficiency option for SMPS applications.

The RFC0807 series is available with 39 inductance values ranging from 12µH to 18mH, with saturation current (Isat) ratings up to 6.65A and DC resistance as low as 0.035Ω. They have a maximum diameter of 8.8 and height of 7.5mm.

The RFC0810 series is offered in 34 inductance values between 33µH and 18mH, with Isat ratings as high as 4.25A and DCR down to 0.065Ω. They have a maximum diameter of 9.5 and height of 11.5mm.

For even greater efficiency, Coilcraft also offers the RFC1010 series in 30 inductance values from 68µH to 18mH, with Isat ratings up to 3.94A and DCR as low as 0.100Ω. They have a maximum diameter of 11.0 and height of 11.5mm.

All RFC family power inductors are halogen free and feature RoHS-compliant terminations. The RFC0810 and RFC1010 also feature a flame-retardant polyolefin wrap to protect the winding.

Pricing starts at $0.24 each in 1,000 unit quantities. Free evaluation samples are available.
