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. Only the ES and HB grade products are tested at three temperatures. The B and C grade products are tested at one temperature. Please refer to the ESS
table on Page 11 for details.
