Where can you get UL certificates or files for a part?

If there is a problem locating UL information applications engineering can assist in locating UL file numbers for a specific part.

However once you have the UL file number in order to get the most recent documents you will need to go to [UL.com](http://UL.com) directly.

There is an easy search tool once you have the file number you can enter it here in the [Online Certification Director.](http://database.ul.com/cgi-bin/XYV/template/LISEXT/1FRAME/index.html).

Search through DK website and manufacturer website or datasheet, If a UL file number is listed on any of this documentation, direct to [www.ul.com](http://www.ul.com/) where you can find details on the file number.  
DigiKey TechForum can be contacted if further documentation is required.

TE’s UL, documentation, or other files can be found [here](https://www.te.com/commerce/DocumentDelivery/DDEController), just search the manufacturer part number for a list of documentation.

If you want to receive the parts with the manufacturer’s **UL marking on the packaging** , you will need to purchase the full reel/tray quantity from DK. DigiKey’s packaging will not reflect any UL markings or certifications because that has to come from the manufacturer who received the UL certification/registration.

If there is absolutely no indication that the part is UL/CSA approved this typically means that the manufacturer has not sought out UL/CSA approval for this product. If you are wondering about why the part is not approved then we would direct you to contact manufacturer directly.
