GS4A0251R1GFT Description

The GS4A0251R1GFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. Housed in an 8-pin narrow SOIC package, it features four isolated thin-film resistors, each with a 51.1Ω resistance and a tight ±2% absolute tolerance. The device operates over a wide temperature range of -70°C to +125°C, with a derated power capability up to 125°C. Its ±50ppm/°C temperature coefficient ensures stable performance in varying thermal conditions. The SOIC-C series construction offers 0.1W (1/10) power rating per resistor (0.4W total), with a 100V maximum voltage rating, making it suitable for demanding circuits.
