GS7B031802FCT Description

The GS7B031802FCT from TT Electronics/IRC is a high-precision 14-pin narrow SOIC ceramic resistor network, designed for demanding applications requiring stable performance under varying conditions. This bussed (BUS) configuration integrates 13 thin-film resistors, each with a 18KΩ resistance value and a tight ±1% absolute tolerance, ensuring consistent signal integrity. The device operates within a wide temperature range of -70°C to +125°C, with a derated power capability up to 125°C, making it suitable for harsh environments. Its ±25ppm/°C temperature coefficient and ±0.25% ratio tolerance further enhance reliability in precision circuits. Encased in a rectangular ceramic SOIC package, it offers robust mechanical stability and excellent thermal dissipation.
