Notes
1
Specifications typical at Ta=+25℃, resistive load, nominal input voltage and rated output current unless otherwise noted.
2
Ripple & Noise measurement bandwidth is 0-20MHz.
3
These power converters require a minimum output loading to maintain specified regulation, operation under no-load conditions will not
damage these modules; however they may not meet all specifications listed.
4
All DC/DC converters should be externally fused at the front end for protection.
5
That “natural convection” is about 20LFM but is not equal to still air (0 LFM).
6
Specifications subject to change without notice.
