GS4A033570DBT Description

The GS4A033570DBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC package, this isolated-element network features four thin-film resistors, each with a resistance value of 357Ω and an absolute tolerance of ±0.5%. The device operates over a wide temperature range of 70°C to 125°C with a derated power rating, ensuring reliable performance in thermally challenging environments. Its ±25ppm/°C temperature coefficient and ±0.1% ratio tolerance make it ideal for precision analog circuits. The SOIC-C series construction provides excellent stability and low noise, while the gull-wing termination facilitates easy surface-mount assembly.
