The suffix “UF” compared to “TF” is explained in the datasheet for the part [VSSR16-220-JI-ND](https://www.digikey.com/en/products/detail/vishay-thin-film/VSSR1603221JUF/1867906?s=N4IgTCBcDaIGoGUECUCMA2ADAZjGVAUgKoBiIAugL5A); [VSSR1603221JUF](https://www.digikey.com/en/products/detail/vishay-thin-film/VSSR1603221JUF/1867906?s=N4IgTCBcDaIGoGUECUCMA2ADAZjGVAUgKoBiIAugL5A). UF means tube packaging while TF means a full reel containing 2500 pieces. This info is on page 3.
