1) Open Circuit Inductance Test Parameters: 100kHz, 0.250 Vrms, 0.0 Adc

Parallel: (1,4 - 3,2) Series: (1 - 3) tie (2 - 4)

2) Peak current for approximately 30% roll-off

3) RMS current, delta temp. of 40° C ambient temperature of 85° C

4) DCR @ 20°C

5) Hipot rating: winding to winding: 300Vdc min.

6) Turns Ratio: (1-2):(4-3) 1:1

7) Applied volt-time product (v-us) across the inductor. This value represents the

applied V-us at 300KHz necessary to generate a core loss equal to 10% of the

total losses for a 40°C temperature rise.
