MEJ1 & MEJ1T Isolated 1W DC/DC Converters

Murata Power Solutions MEJ1 and MEJ1T 1W DC/DC Converters are isolated 5.2kVDC and 6kVDC devices with a SIP footprint. The MEJ1 series features single- and dual-output converters that are pin compatible with the existing Murata series but offer improved efficiency and regulation. The MEJ1 converters are UL 60950-recognized for basic/supplementary isolation and UL 60601-3rd Edition recognized. The MEJIT variant offers UL 62368-1 recognition. Murata Power Solutions MEJ1 Isolated 1W DC/DC Converters are suitable for use where safety and miniaturization are important, such as medical and industrial applications.
