GS4A022801DBT Description

The GS4A022801DBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC package, it features four isolated thin-film resistors, each with a 2.8KΩ resistance and an absolute tolerance of ±0.5%. The device operates over a wide temperature range of -55°C to +125°C, with a derated power range of 70°C to 125°C, ensuring reliability in harsh environments. Its ±50ppm/°C temperature coefficient and ±0.1% ratio tolerance make it ideal for precision analog circuits. The SOIC-C series construction provides excellent thermal stability and low noise, while the 100V maximum voltage rating and 0.4W total power dissipation enhance its versatility.
