RFB0807 Series

Power Inductors

For values >10uH, we recommend the RFC0807B for new designs. The RFC series is a halogen-free, drop-in replacement for the RFB and offers lower DCR and better current ratings. We will continue to manufacture and support all values of the RFB0807 series.

Coilcraft RFB0807 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. RFB0807 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)
