The data sheets on this site are PDF (Portable Document Format) files. PDF is a standard in widespread use for electronic transmission of documents containing text, graphics or photos.  Although the original document might have been created by us using a sophisticated word-processing or graphics package, once we have converted the data into a PDF file then your computer doesn't need to have the original package installed in order to read the file - all you need is a PDF reader program.

If your computer doesn't have a PDF reader program already installed, you can download the Acrobat Reader free of charge from the manufacturer's web site.
