When operated with additional external load capacitance the rise time of the input voltage will determine the maximum external
capacitance value for guaranteed start up. The slower the rise time of the input voltage the greater the maximum value of the
additional external capacitance for reliable start up.

PRODUCT OVERVIEW
6.0
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

1. Calculated using MIL-HDBK-217 FN2 calculation model with nominal input voltage at full load.
2. See derating graph.
3. Supply voltage must be discontinued at the end of the short circuit duration.
4. See ripple & noise test method.
