Texas Instruments Samples

On the Texas Instruments site, what does /250 and /2k5 mean on the sample codes?


I understand the G4 bit sometimes added is relating to the lead content.



I thought it might be the number of items received... but I just got a package through (and luckily) I only got one of each item.

Cheers

Taken from a random part datasheet: "NOTES: (1) Models with a slash (/) are available only in Tape and Reel in the quantities indicated (e.g., /2K5 indicates 2500 devices per reel). Ordering 2500 pieces of “INA155UA/2K5” will get a single 2500-piece Tape and Reel."
