The component lead termination of this product range is leadfree compatible, therefore the converter can be soldered in a lead-free soldering process. The devices are fully compatible with CECC00802 to 280C which allows them to be placed and reflowed with IC's, thus reducing time and cost in production. Coplanarity of the lead positions is based upon IEC 191-6:1990. The devices are suitable for all applications where high volume production is envisaged.

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