Specifications typical at Ta=+25℃, resistive load, nominal input voltage and 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.
The MJWI20 series can meet EN55022 Class A with parallel an external LC Filter to the input pins. Please refer to Test Configurations on the last page.
To order the converter with heatsink, please add a suffix -HS (e.g. MJWI20-24S05-HS) to order code.
Specifications are subject to change without notice.
