GS4A022740FBT Description

The GS4A022740FBT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a resistance value of 274Ω and a tight ±1% absolute tolerance (with ±0.1% ratio tolerance). Its SOIC-C series construction ensures robust performance in demanding environments, with a temperature coefficient of ±50ppm/°C for stable operation across a wide temperature range (70°C to 125°C). The network is rated for 0.1W per resistor (0.4W total) and supports a maximum voltage of 100V, making it suitable for low-power, high-precision circuits.
