2. Comments

MiniMELF is a cylindrical, surface mount component package whose most common use is for packaging diodes and resistors. This package often comes under the alternative names SOD-80 or DO-213AA. I prefer to call it MiniMELF as it’s to remember when there are a plethora of other packages under the "SOD" or "DO-" naming convention.

MiniMELF (and all the other packages in the MELF family) are cylindrical shaped components. This makes them somewhat infamous because they have a tendency to roll around when soldering. This leads to the backronym "MELF: Most End up Lying on the Floor" or being called the "roll away" package. However, they remain popular because offer significant advantages over traditional SMD packages including:
