TE Connectivity R Series Precision Resistor 47.5kΩ 0.25W Axial

The TE Connectivity R Series precision metal film fixed resistor is engineered for applications where long-term stability is crucial. Constructed with a resistive element comprising a thin film of nickel-chrome alloy evaporated onto a high thermal conductivity ceramic core, this component ensures reliable and consistent performance.

Metal end caps are force-fitted to the element prior to spiralling to value, while tinned copper lead wires are welded to the end caps for secure connectivity. The resistor is then coated with one coat of phenolic resin followed by three coats of epoxy resin, providing robust protection against environmental factors.

Key Performance Benefits

• Excellent stability under load and severe environmental conditions
• Exhibits very low noise current and voltage coefficients
• Wide operating temperature range from -65°C to 155°C
• High precision with a tight resistance tolerance of ± 0.1%

With a power rating of 250mW (0.25W) and a voltage rating of 500V, this axial leaded resistor is designed for through-hole mounting. It features a temperature coefficient of ± 15ppm/°C, making it suitable for demanding electronic circuits that require precise and stable resistance values over varying temperatures.
