GS4A031820DCT

GS4A031820DCT Description

The GS4A031820DCT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a resistance value of 182Ω 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 rating, ensuring reliable performance in thermally challenging environments. With a low temperature coefficient of ±25ppm/°C and a maximum voltage rating of 100V, this network is engineered for stability and precision. The SOIC-C series construction offers a compact footprint (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations for easy surface-mount assembly.
