The MINMAX MSHU100 series is a new range of 2W DC/DC-converter modules providing a very high I/O-isolation voltage of 4000 VAC. The product
comes in a small SMD-package. There are 15 models available with 5V, 12V or 24VDC input and single-or dual-output voltages.
The MSHU100 DC/DC converters offer an economical solution for many applications in instrumentation, industrial controls, medical equipment and
everywhere where a certified supplementary- or reinforced insulation system is required to comply with requested safety standards.

Specifications typical at Ta=+25℃, resistive load, nominal input voltage and rated output current unless otherwise noted.
Ripple & Noise measurement bandwidth is 0-20MHz.
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.
All DC/DC converters should be externally fused at the front end for protection.
Other input and output voltage may be available, please contact factory.
That “natural convection” is about 20LFM but is not equal to still air (0 LFM).
Specifications subject to change without notice.
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.
