OCL (Open Circuit Inductance) and L at Irms and L at Isat and DCR are measured at: 100kHz, 0.25V at 25°C. 2. Isat : DC current that causes inductance to drop by approximately 30% from OCL; (Ta = 25°C). 3. Irms : DC current that causes an approximate temperature rise (ΔT) of 40°C; (Ta = 25°C). 4. Inductance Vs. DC bias curve, please see the next page to get more detail information. 5. Inductance tolerance: ±20%, Base type: Plastic.
