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
Lead temperature 1.5mm from case for 1ꢀ seconds
Internal power dissipation
The NTV series of 3kV isolation miniature
surface mounted DC/DC converters employ
leadframe technology and transfer moulding
techniques to bring all of the benefits of IC style
packaging to hybrid circuitry. The co-planar-
ity of the pin positions is based upon IEC
191-6:199ꢀ. The devices are suitable for all
applications where high volume production is
envisaged.

1. If components are required in tape and reel format suffix order code code with -R, e.g. NTVꢀ5ꢀ5MC-R.
2. Calculated using MIL-HDBK-217F with nominal input voltage at full load.
3. 12V input types have typically 3% less load regulation change.
4. Supply voltage must be disconnected at the end of the short circuit duration.
All specifications typical at T =25°C, nominal input voltage and rated output current unless otherwise specified.
