GS4A0239R2DDT Description

The GS4A0239R2DDT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding surface-mount applications. Housed in an 8-pin narrow SOIC package, it features four isolated thin-film resistors, each with a resistance value of 39.2Ω and an absolute tolerance of ±0.5%. The device operates over a wide temperature range of -70°C to +125°C, with a derated power capability up to 125°C, ensuring reliability in harsh environments. Its ±50ppm/°C temperature coefficient and 0.1W power rating per resistor (0.4W total) make it suitable for precision analog and digital circuits. The gull-wing termination and 1.27mm terminal pitch facilitate easy PCB integration, while the ceramic case enhances thermal stability and durability.
