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.
