3. Ripple & Noise measurement bandwidth is 0-20
MHz.
Exceeding these values can damage the module. These are not continuous
operating ratings.
4. These power converters require a minimum
output loading to maintain specified regulation.
5. Operation under no-load conditions will not
damage these devices; however they may not
meet all listed specifications.
Environmental Specifications
6. All DC/DC converters should be externally fused at
the front end for protection.
