GS4A021181CBT Description

The GS4A021181CBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring stable performance under varying conditions. Housed in an 8-pin narrow SOIC package, this device features four isolated thin-film resistors, each with a resistance value of 1.18 kΩ and an absolute tolerance of ±0.25%. Its ±50 ppm/°C temperature coefficient ensures minimal resistance drift across the operating range of 70°C to 125°C, making it suitable for precision circuits. The SOIC-C series construction offers robust ceramic substrate reliability, with a 0.1W power rating per resistor (0.4W total) and a 100V maximum voltage rating.
