GS4A034870CT Description

The GS4A034870CT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC package, this device features four isolated thin-film resistors, each with a resistance value of 487Ω and an exceptional ±0.25% tolerance. The network operates over a wide temperature range (70°C to 125°C) with a low temperature coefficient of ±25ppm/°C, ensuring stability in fluctuating thermal conditions. With a power rating of 0.4W (0.1W per resistor) and a maximum voltage rating of 100V, it is engineered for reliability in precision circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case enhances durability and heat dissipation.
