Document 277-1 Power Inductors - RFB Series These low cost power inductors offer a wide range of inductance values, from 2.2 H to 18 mH. They have an open magnetic construction which gives them high current carrying capabilities. The RFB0807 Series offers the lowest profile (7,5 mm) and a standard 5 mm pin spacing. The larger RFB0810 and 1010 Series have the lowest DC resistance and highest current ratings. They also have a PVC wrap to protect the winding. Free evaluation samples are available by contacting Coilcraft or visiting www.coilcraft.com.
