MELF components are SMT components with a rod-shaped, cylindrical component body. The end faces are metallized, usually in the form of caps. In some cases, metal discs are also used as connections. MELF resistors are used less frequently nowadays; the rectangular chip package is more common. However, MELF resistors can offer advantages in maximum thermal dissipation (larger package = larger surface area), dielectric strength, pulse load capability, long-term stability, and temperature stability. MELF diodes are manufactured with plastic or glass bodies.
