GS4A012210CBT Description

The GS4A012210CBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring stable performance under varying thermal conditions. Housed in an 8-pin narrow SOIC package, this 4-resistor isolated network features 221Ω resistance per element with an absolute tolerance of ±0.25% and a ratio tolerance of ±0.1%, ensuring exceptional accuracy. Its thin-film technology and ±100ppm/°C temperature coefficient provide reliable operation across a wide temperature range (70°C to 125°C). The SOIC-C series construction offers robust ceramic substrate durability, while the gull-wing termination facilitates secure surface-mount (SMD) assembly. With a power rating of 0.1W per resistor (0.4W total) and a maximum voltage rating of 100V, this component is ideal for precision analog and digital circuits.
