RFB1010-121L

We will continue to manufacture and support the all values of the RFB1010 series indefinitely, however, for values >56 µH we recommend the RFC1010 for new designs. The RFC series is a halogen-free, drop-in replacement for the RFB and offers lower DCR and better current ratings.

Notes

When ordering, please specify termination codes: e.g. RFB1010-183L
Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc 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 a 10% (typ) 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.

Termination:

L = RoHS compliant tin-silver over tin over copper over steel.
T = RoHS tin-silver-copper (95.5/4/0.5). (Special order, added cost)
S = non-RoHS tin-lead (63/37). (Special order, added cost)
