Notes

When ordering, please specify packaging code: e.g. ZB1201-CEC
Inductance measured per winding (ZB1200, pins 1-6, 1-4, 3-6) at 100 kHz, 0.1 V, 0 Adc on an Agilent/HP 4192 or equivalent.
DCR measured at 25°C on a micro-ohmmeter. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.

Termination:

E = RoHS compliant tin-silver-copper over silver-platinum-glass frit.
