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.

1. If components are required in tape and reel format suffix order code with -R, e.g. NTA0505MC-R.
2. Calculated using MIL-HDBK-217F with nominal input voltage at full load.
All specifications typical at TA=25°C, nominal input voltage and rated output current unless otherwise specified.
