MKW3000 Series
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 4.7uF
capacitors at the output.

Maximum Capacitive Load
The MKW3000 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 270uF
maximum capacitive load for dual outputs, 680uF capacitive
load for 12V & 15V outputs and 6800uF capacitive load for
3.3V & 5V outputs.
The maximum capacitance can be found in the data sheet.
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 105°C.
The derating curves are determined from measurements
obtained in an experimental apparatus.
