Notes
1
Specifications typical at Ta=+25℃, resistive load, nominal input voltage, rated output current unless otherwise noted.
2
Ripple & Noise measurement bandwidth is 0-20 MHz.
3
All DC/DC converters should be externally fused at the front end for protection.
4
Other input and output voltage may be available, please contact factory.
5
The PM05S series can meet EN61000-4-4 by adding a capacitor across the input pins. Suggested capacitor CHEMI-CON KY
330μF/100V.
6
That “natural convection” is about 20LFM but is not equal to still air (0 LFM).
7
It needs to increase 1V for Vin(min) under high and low temperature.
8
Specifications are subject to change without notice.
