RFC0810B Series

Power Inductors

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. 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

When ordering, please specify lead length and termination codes: e.g. RFC0810B-183KE
Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc; measured on an Agilent/HP 4284A LCR meter or equivalent.
DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
SRF measured using an Agilent/HP 4191A or equivalent. Details
Isat: DC current at 25°C that causes the specified inductance drop from its value without current. Temperature derating curves.
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.

Lead Length:

A = 3.6 mm ±0.3 mm (special order)
B = 5.0 mm ±0.5 mm
C = 7.0 mm ±0.5 mm (special order)
D = 8.0 mm ±0.5 mm (special order)
E = 10.0 mm ±1.0 mm (special order)
F = 25.0 mm ±1.0 mm, packaged in fanfold tape, 800 parts per box (special order)

Termination:

E = RoHS compliant tin-silver over tin over copper over steel.
S = non-RoHS tin-lead (63/37). (Special order, added cost)
