MELF (Metal Electrode Leadless Face) is a 2-lead cylindrically-shaped SMD component package. It is a hermetically sealed glass-based package, which offers components with superb reliability characteristics1. However, they are not very popular because they have a tendency to roll around when soldering. Jokingly they can be referred to as “Most End up Lying on the Floor”.
