GS4A0276R8DDT Description

The GS4A0276R8DDT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a resistance value of 76.8Ω and an absolute tolerance of ±0.5%. The network operates within a wide temperature range of -55°C to +125°C, with a derated power range of 70°C to 125°C, ensuring reliable performance under varying thermal conditions. Its ±50ppm/°C temperature coefficient guarantees minimal resistance drift, making it ideal for precision circuits. The SOIC package (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations and 1.27mm pitch facilitates easy surface-mount assembly. Rated for 100V maximum voltage and 0.1W power dissipation per resistor, it is suitable for low-power, high-density designs.
