MINIMELF (SOD-80, DO-213AA) COMPONENT PACKAGE
MiniMELF (SOD-80, DO-213AA) Component Package
3.2mm (distance between terminal centers)
Easy to solder by hand, but doesn’t stay in one place! Can also be wave or reflow soldered.
3.5mm length, 1.5mm diameter
Typical PCB Land Area
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:
