FEATURES
PRODUCT OVERVIEW
The NTE series of miniature surface mounted
DC/DC Converters employ leadframe technol-
ogy and transfer moulding techniques to bring
all of the benefits of IC style packaging to hybrid
circuitry. The co-planarity of the pin positions is
based upon IEC 191-6:1990. 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. NTE0505MC-R.
2. Calculated using MIL-HDBK-217 FN2 calculation model with nominal input voltage at full load.
3. Supply voltage must be disconnected at the end of the short circuit duration.

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.
