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.

---|---|---|---|---|
(RFM) Non-Inductive Melf for High Frequency Application
RFM series, resistance range (25Ω to 200Ω), tolerance range (±0.5% to ±5.0%), power dissipation rating at 70°C up to 0.75W, small size. They are the perfect choice in high frequency circuit designs where the parasitic inductance of regular, helical trimmed resistors can not be accepted, but where also pulse energies apply. Typical applications are in the fields of telecommunication equipment and industrial electronics.
