The OD121JE is a Carbon Composition Resistor manufactured by extruding a blend of carbon and organic binders inside a phenolic outer body with solder-coated copper terminal. The extrusion is cut to length, leads inserted, cured and marked to form a finished resistor. This fixed resistor is made tough by a molding process that combines the terminals, insulation and resistive element into an integrated unit. Along with their small size, Little Demons? perform with low noise, dissipate heat rapidly and offer high temperature stability. This resistor is able to withstand larger short-term pulses and higher voltages than film resistors. It is sensitive to moisture and therefore, storage recommendations should be adhered to. The resistor is highly hygroscopic and changes in resistance value can occur if too much moisture is absorbed. For this reason, alcohol or hydrocarbon solvents are recommended for rinsing.
