Note :
1. OCL (Open Circuit Inductance) and L at Irms and L at Isat and DCR are measured at: 100 KHz,0.25 V at 25ºC.
2. Isat : DC current that causes inductance to drop by approximately 30% from OCL ; (Ta = 25ºC).
3. Irms : DC current that causes an approximate temperature rise (∆T) of 40°C ; (Ta = 25ºC).
