PRODUCT OVERVIEW
The NMJ series are dual and single output
DC/DC converters in a 7 pin SIP package style
offering pin and functionality compatibility with
the NMV series SIP DC/DC converters. The NMJ
series is UL60950 recognized and suitable for
applications where safety and miniaturisation
are of paramount importance. Isolation barrier
approved for supplementary/reinforced insulation
- see page 2.
