Notes

When ordering, please specify termination code: e.g. B0570-BL
Inductance is for the primary, measured at 10 kHz, 0.1 Vrms, 0 Adc.
DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Leakage inductance measured at 100 kHz, 0.1 Vrms.
Isolation tested between primary and secondary and between primary and auxiliary windings for one minute.

Termination:

L = RoHS compliant tin-silver over tin over copper.
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)
