When looking at Micron memory products, you may see “TR” at the end of these part numbers, such as MT25QL01GBBB8ESF-0SIT TR and MT29F8G16ADBDAH4-AIT:D TR. This last suffix “TR” is not always called out in the manufacturer datasheet.
When ordering a tape and reel carrier for most Micron memory products, “TR” must be added to the ordering part number.
