Electrical Characteristics Notes

1. While the filter will survive these input voltage limits, the filter’s output voltage will be outside the limits for an MQFL converter input voltage range.

2. Verified by qualification testing and analysis.

3. Derate filter output power to 320W during a 60V input surge, to 240W at an 80V input surge, and to 180W at a 100V or 110V input surge.

4. Only the ES and HB grade products are tested at three temperatures. The C grade products are tested at one temperature. Please refer to the

Construction and Environmental Stress Screening Options table for details.

5. Soft start is engaged only when the output voltage starts from zero or dips below the Turn-Off Output Voltage Threshold (4V max).

6. The specified operating case temperature for ES grade products is -45ºC to 100ºC. The specified operating case temperature for C grade products is

0ºC to 70ºC.
