DESCRIPTION
The NTH 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 hy-
brid circuitry. The component lead termination
of this product range is lead-free compatible,
therefore the converter can be soldered in a
lead-free soldering process. 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.
