Note:
1. Test Frequency：100KHz / 1.0Vdc
2. Testing Instrument : L:HP-4284A, CH3302, CH-1320, CH-1320S LCR METER ; DCR:502 OHMMETER
3. Operating temperature - 40℃ ~ +125℃
4. All test data is referenced to 25℃ ambient.
5. Irms(A) will cause an approximately temp. rise ΔT≦40℃ (keep 1 min).
6. Isat (A) will cause L0 to drop approximately 20%
7. Hi-Pot：Core to Wire of withstanding voltage, add 200Vdc / ≦3mA .
8. Insulation resistant：Core to Core of resistance .
9. The part temperature (ambient + temp rise) should not exceed 125℃under worst case operating conditions. Circuit
design, component, PCB trace size and thickness, airflow and other cooling provisions all affect the part temperature.
Part temperature should be verified in the end application.
10.Special inquiries besides the above common used types can be met on your requirement.
