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;
4
All DC/DC converters should be externally fused at the front end for protection.
however they may not meet all specifications listed.
5
Other input and output voltage may be available, please contact factory.
6
That “natural convection” is about 20LFM but is not equal to still air (0 LFM).
7
Specifications subject to change without notice.
8
It is not recommended to use water-washing process on SMT units.

Test Configurations
Peak-to-Peak Output Noise Measurement Test
Use a Cout 0.47uF ceramic capacitor. Scope measurement should be made by using a BNC socket, measurement bandwidth is 0-20 MHz. Position the load between
50 mm and 75 mm from the DC/DC Converter.

Design & Feature Considerations
Maximum Capacitive Load
The MSHU100 series has limitation of maximum connected capacitance at the output. The power module may be operated in current limiting mode during start-up,
affecting the ramp-up and the startup time. For optimum performance we recommend 100uF maximum capacitive load for dual outputs and 330uF capacitive load for
single outputs. The maximum capacitance can be found in the data sheet.
Input Source Impedance
The power module should be connected to a low ac-impedance input source. Highly inductive source impedances can affect the stability of the power module. In
applications where power is supplied over long lines and output loading is high, it may be necessary to use a capacitor at the input to ensure startup.
Capacitor mounted close to the power module helps ensure stability of the unit, it is recommended to use a good quality low Equivalent Series Resistance (ESR <
1.0Ω at 100 KHz) capacitor of a 2.2uF for the 5V input devices, a 1.0uF for the 12V input devices and a 0.47uF for the 24V input devices.

Output Ripple Reduction
A good quality low ESR capacitor placed as close as practicable across the load will give the best ripple and noise performance. To reduce output ripple, it is
recommended to use 3.3uF capacitors at the output.

Thermal Considerations
Many conditions affect the thermal performance of the power module, such as orientation, airflow over the module and board spacing. To avoid exceeding the
maximum temperature rating of the components inside the power module, the case temperature must be kept below 90℃. The derating curves are determined from
measurements obtained in a test setup.
