When operated with additional external load capacitance the rise time of the input voltage will determine the  
maximum external capacitance value for guaranteed start up. The slower the rise time of the input voltage the  
greater the maximum value of the additional external capacitance for reliable start up.

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

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. NTE0505M-R
