DESCRIPTION
The NTH 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. The component
lead termination of this product range is lead-
free compatible, therefore the converter can
be soldered in a lead-free soldering process.
The devices are fully compatible with

ISOLATION CHARACTERISTICS
CECC00802 to 280°C which allows them to
be placed and reflowed with IC’s, thus
reducing time and cost in production. Co-
planarity of the lead positions is based upon
IEC 191-6:1990. The devices are suitable for
all applications where high volume

1 Calculated using MIL-HDBK-217F with nominal input voltage at full load.
2 See derating curve.
3 12V input types have typically 3% less load regulation change.
4 Supply voltage must be discontinued at the end of the short circuit duration.
5 If components are required in tape and reel format suffix order code with -R, e.g. NTH0505M-R
All specifications typical at TA=25°C, nominal input voltage and rated output current unless otherwise specified.
