## **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).
4. Inductance Vs. DC bias curve, please see the next page to get more detail information.
5. Inductance tolerance: ±20%, Base type: Plastic.
