Specifications typical at Ta=+25℃, resistive load, nominal input voltage, rated output current unless otherwise noted.
Transient recovery time is measured to within 1% error band for a step change in output load of 75% to 100%.
Ripple & Noise measurement bandwidth is 20 MHz, measured with a 1μF MLCC and a 10μF Tantalum Capatitor.
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.
To order the converter with heatsink, please add a suffix -HS (e.g. MJW25-24S05-HS) to order code.
The MJW25 series can meet EN61000-4-4 & EN61000-4-5 by adding a capacitor across the input pins.Suggested capacitor:CHEMI-CON KY 220μF/100V.
That “natural convection” is about 20LFM but is not equal to still air (0 LFM).
Specifications are subject to change without notice.
