GS4A032212DBT Description

The GS4A032212DBT 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 22.1 kΩ and an absolute tolerance of ±0.5%. 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 stability in harsh environments. Its ±25 ppm/°C temperature coefficient and ±0.1% ratio tolerance make it ideal for precision analog circuits. The SOIC package (4.9 mm × 5.99 mm × 1.45 mm) with gull-wing terminations ensures reliable surface-mount assembly.
