RJM resistor MELF Resistors also can be called a wafer resistance, cylindrical-type resistance, non-pin resistance, or non-lead resistance, mainly used for surface mount processing. No pin wafer and chip resistor (SMD) resistors, the same for surface mount components, wafer resistor function, mechanical structure, electrical properties, the safety of the obviously superior chip (chip) resistors, and the noise lower than the thick-film chip resistors. Cylindrical MELF resistors are applied to power type / high impact type / precision / high-end security requirements of high circuit.
