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. By similarity to the qualification testing and analysis of the MQME-270-P filter.

3. 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.

4. Product of input current and output voltage must be less than 160W

5. The specified operating case temperature for ES grade products is -45°C to 100°C. The specified operating case temperature for C grade products is 0°C to

70°C.
