FEATURES

NMJ series

PRODUCT OVERVIEW

The MEJ2 series are single and dual output

medically approved DC/DC converters in a 7 pin SIP

package style offering a power upgrade path from

the NMJ series SIP DC/DC converters. The MEJ2

series is UL 60950 and UL 60601 recognized, which

makes it ideal for applications where safety and

miniaturisation are of paramount importance.
