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

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
