Test Remarks:
- All test data is referenced to 25 ambient.
- Isat: DC current at which inductance drops approximate 30% from its value without current.
- Irms: DC current that causes the temperature rise (T 40 ) from 25 ambient.
4. General Specification
- Operating Temperature: -40 ~ +85 (Including self-generated heat)
- Storage Temperature: -10 ~ +40, R.H.: 60% Max.
- Recommended Usage: Within 12 months from the date of delivery.
- Part Temperature Limit: The part temperature (ambient + temp rise) should not exceed 85 C under worst-case operating conditions. Verification in the end application is recommended.
5. Soldering Conditions
- Re-flow Soldering (Lead Free): Preheat to 150, tip temperature max 260. Reflow times: no more than 2. Solder paste thickness: best 0.08mm, max 0.1mm.
- Hand Soldering: Use a 20 watt soldering iron with a 1.0mm tip diameter. Limit soldering time to 3 sec.
6. Appearance Defect Judging Standard
- Copper wire exposed in magnetic shield area: Less than 0.06 square millimeter is acceptable.
