Note:

1. All test data is referenced to 26

ºC ambient.

2. Inductance is measured by LCR meter, Test frequency at 1MHz

3. Inductance Tolerance:

±20%.

4. DC resistance is measured by micro-ohm meter.

5. Isat means that DC current will cause a 30% inductance reduction form initial value.

6. Irms means that DC current will cause coil temperature rising to 40

ºC whichever is smaller.
