What the code "M" in the LT1761 part number means?

[steven.vansanten]

What is the difference between the following part numbers?
LT1761ES5-3.3#TRMPBF
LT1761ES5-3.3#TRPBF
Yes, I know one part number has the M and and the other does not.
The M is not mentioned in the datasheet.
What does the M designate?

This is actually calling out a mini-reel from the factory. No difference in the actual part just the packaging.

TRMPBF suffix vs. TRPBF suffix in Linear Technology parts

Linear Technology sells many of their parts on different sized reels. The “mini” 500 piece reel will have a suffix of TRMPBF, while the larger 2500 piece (and often non-stock) reel will have a TRPBF suffix. This information is not found on any of Linear Technology’s datasheets. Click here for a comparison of the two part numbers : LTC2050CS5# Search
