Notes
Specifications typical Ta=+25], resistive load, nominal input voltage, rated output current unless otherwise noted. Ripple Noise measurement bandwidth 0-20 MHz. These power converters require minimum output loading maintain specified regulation. Operation under no-load conditions will damage these modules; however, they meet specifications listed. DC/DC converters should externally fused front protection. Other input output voltage available, please contact factory. Specifications subject change without notice.

Thermal Considerations
Many conditions affect thermal performance power module, such orientation, airflow over module board spacing. avoid exceeding maximum temperature rating components inside power module, case temperature must kept below derating curves determined from measurements obtained experimental apparatus.
Design Feature Considerations
Maximum Capacitive Load
MSAU100 series limitation maximum connected capacitance output. power module operated current limiting mode during start-up, affecting ramp-up startup time. optimum performance recommend 33uF maximum capacitive load. maximum capacitance found data sheet.

Input Source Impedance
power module should connected ac-impedance input source. Highly inductive source impedances affect stability power module. applications where power supplied over long lines output loading high, necessary capacitor input ensure startup.
