1. If components are required in tape and reel format suffix order code with -R, e.g. NTE0505MC-R.
2. Calculated using MIL-HDBK-217 FN2 calculation model with nominal input voltage at full load.
All specifications typical at T
A=25°C, nominal input voltage and rated output current unless otherwise specified.
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.
