GS4A033240FBT Description

The GS4A033240FBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 4-resistor isolated network features a 324Ω resistance value with a tight ±1% absolute tolerance and an exceptional ±0.1% ratio tolerance, ensuring superior matching accuracy. Encased in an 8-pin narrow SOIC (SOIC-C) package, it employs thin-film technology for stable performance across a wide temperature range (70°C to 125°C). With a ±25ppm/°C temperature coefficient, it delivers minimal resistance drift, making it ideal for precision circuits. The 0.1W (1/10W) power rating per resistor and 100V maximum voltage rating ensure reliable operation in compact, surface-mount designs.
