NOTES

1. Transient recovery time is measured to within 1% error band for a step change in output load of 75% to 100%.

2. The MSKUW series requires a minimum output loading to maintain specified regulations. Operation under no-load conditions will not

damage these devices, however they may not meet all listed specifications.

3. All DC/DC converters should be externally fused at the front end for protection.

4. Other input and output voltages may be available, please contact factory.

5. It is not recommended to use the water-washing process on SMT units.
