The R series from TE Connectivity offers a highly reliable range of precision metal film fixed resistors. These resistors offers high precision with a tolerance to 0.1% and temperature coefficients to 15ppm. The range provides great stability under heavy load and different environmental conditions and can be used in a wide -65°C to +155°C operating temperature making them perfect for applications where long-term stability is essential.

Precision Metal Film Fixed Resistors

The resistive element comprises a thin film of nickel-chrome alloy evaporated onto a high thermal conductivity ceramic element. Metal end caps are force fitted to the element prior to spiralling to value. Tinned copper lead wires are welded to the end caps and the components are then coated. One coat of phenolic resin is followed by three coats of epoxy resin. All resistors are tested for value and tolerance.

Precision metal film resistors with tolerance to 0.1% and temperature coefficients to 15ppm
Metal film resistors have excellent stability under load and severe environmental conditions. They exhibit very low noise current and voltage coefficients. Precision metal film resistors are particularly suitable in all applications where long-term stability is important.
