MELF RESISTORS

MELF RESISTORS

MELF is the acronym for Metal Electrode Leadless Face - a leadless cylindrical component that is metallized on two ends. It is designed majorly as a SMD (Surface Mounting Device) component. Since manufacturing process of MELF resistor is more complex than flat-chip resistor, MELF resistor has its own advantages over flat-chip type.

DIRECT Passive Electronics offers MELF resistors including ultra precision, high pulse load, and common type with more stability, moisture proof, low TCR, compacted size. Full lines meet RoHS Directives, MIL-R-10509, MIL-R-55182, and other military grade.
