Metal electrode leadless face

MiniMelf diode

Metal electrode leadless face (MELF) is a type of leadless cylindrical electronic surface mount device that is metallized at its ends. MELF devices are usually diodes and resistors.[1]

The EN 140401-803 and JEDEC DO-213 standards describe multiple MELF components.[2]
