Metal Film Fixed Resistors Type LR Series Key Features � Superior quality metal film resistors with 1% tolerance and temperature coefficients down to 50 ppm. 3 case sizes are available in 0.25, 0.6, 0.75W. The LR1L series is a low ohmic value range from 0.1 to 0.82 ohm. Ideally suited where low resistance and small size are required. � Metal film resistors have excellent stability under load and severe environmental conditions. They exhibit very low noise current and voltage coefficients. The resistive element comprises a thin film of nickel-chrome alloy evaporated onto a high They are available in a thermal conductivity ceramic element. Metal end caps are force fitted to the element prior wide range of resistance to spiralling to value. Tinned copper lead wires are welded to the end caps and the values and are suitable components are then coated. One coat of phenolic resin is followed by three coats of for general purpose and precision epoxy resin. All resistors are tested for value and tolerance. applications.
