1. When ordering, please specify termination code:
B0570-BL
Termination:L=RoHS compliant tin-silver over tin over nickel over
phos bronze. Special order:
T = RoHS tin-silver-copper (95.5/4/0.5) or
S = non-RoHS tin-lead (63/37).
2. Inductance is for the primary, measured at 10 kHz, 0.1 Vrms, 0 Adc.
3. Leakage inductance tested at 100 kHz, 0.1 Vrms
4. Isolation tested between primary and secondary and between primary
and auxiliary windings for one minute.
5. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
