Test Remarks:
(1). All test data is referenced to 25 ambient.
(2). 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 Period: Within 12 months from the date of delivery
- Part Temperature Limit: Should not exceed 85 C under worst-case operating conditions (ambient + temp rise). Verification in end application is required.
5. Soldering Conditions
- Re-flow Soldering (Lead Free): Preheat to 150; Max tip temperature 260; Reflow times: no more than 2 times; Solder paste thickness: 0.08mm (best), 0.1mm (max).
- Hand Soldering: Use a 20 watt soldering iron with tip diameter of 1.0mm; Limit soldering time to 3 sec.
6. Appearance Defect Judging Standard
- Copper wire exposed: Area of copper wire exposed in magnetic shield area less than 0.06 square millimeter is OK.
