Notes:
- All test data is referenced to 25 °C ambient.
- Operating temperature range: -55 °C to +125 °C (ambient plus self-temperature rise).
- Idc(A): DC current (A) that will cause an approximate ΔT of 40 °C (reference ambient temperature is 25 °C).
- Isat(A): DC current (A) that will cause L0 to drop approximately 30 %.
- The part temperature (ambient + temp rise) should not exceed 125 °C under worst-case operating conditions. Part temperature should be verified in the end application.
Environmental Data:
- Storage temperature range: -55 °C to +125 °C
- Operating temperature range: -55 °C to +125 °C (ambient plus self-temperature rise)
- Solder reflow temperature: J-STD-020 compliant
