RFB1010 Series
Power Inductors

New RoHS part numbers are shown. Lead was removed from terminations. The last character is now L to indicate RoHS compliance. (View old data sheet.)

Low cost, high efficiency option for choke applications
Inductance values from 10 µH to 18 mH
Current ratings up to 6 Amps
Flame retardant polyolefin wrap protects the windings
500 V isolation from winding to core
RoHS-compliant. Tin-silver over tin over copper over steel terminations.
For smaller sizes see RFB0807 and RFB0810

1	Inductance tested at 100 kHz, 0.1 Vrms; measured on an Agilent/HP 4263B LCR meter or equivalent.
2	SRF measured using an Agilent/HP 4191A or equivalent. Details
3	Isat: DC current at which the inductance drops 10% (typ) from its value without current. Details
4	Irms: Current that causes the specified temperature rise from 25°C ambient. Details
5	Ambient temperature range:	–40°C to +85°C with Irms current.
6	Storage temperature range:	Component: –40°C to +85°C Packaging: –55°C to +80°C
7	Electrical specifications at 25°C.
Refer to Soldering Coilcraft Components before soldering.
