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