A=25°C, nominal input voltage and rated output current unless otherwise specified.
PRODUCT OVERVIEW
The NTA series of 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. Co-planarity of the
lead positions is based upon IEC 191-6:1990. The
devices are suitable for all applications where
high volume production is envisaged.
