GS4A022052FAT Description

The GS4A022052FAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a resistance value of 20.5 kΩ and an absolute tolerance of ±1%. The network operates over a wide temperature range of -70°C to +125°C, with a derated power range of 70°C to 125°C, ensuring reliability in harsh environments. Its ±50 ppm/°C temperature coefficient and ±0.05% ratio tolerance make it ideal for precision analog circuits. The SOIC package (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations ensures compatibility with standard surface-mount assembly processes.
