GS4A022740CT

GS4A022740CT Description

The GS4A022740CT 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 274Ω resistance and an exceptional ±0.25% tolerance. Its ±50ppm/°C temperature coefficient ensures stable performance across a wide operating temperature range of 70°C to 125°C, making it suitable for environments with thermal fluctuations. The SOIC-C series construction offers robust ceramic case durability, while the gull-wing termination facilitates reliable surface-mount (SMD) assembly. With a maximum voltage rating of 100V and a power rating of 0.4W (0.1W per resistor), this network balances precision and power efficiency.
