notes

1. guaranteed by qualification test and/or analysis. not an in-line test.

2. For MHF+281r9, load regulation is tested from a 10 ma load to full load.

3. indefinite short circuit protection not guaranteed above 125°C (case).

4. recovery time is measured from application of the transient to the point at which

VOuT is within regulation.

5. Step transition time >10 µs.

6. Step transition time 100 µs ±20%

7. Step line is 20 - 32 - 20 volts for MHF+281r39S.

8. Measured on release from inhibit.

9. no effect on dc performance.

table 6: eleCtriCal CharaCteristiCs -55°C to +125°C Case, 28 vin, 100% loaD, Free run, unless otherwise sPeCiFieD.
