GS4B032002CBT Description

The GS4B032002CBT from TT Electronics/IRC is a high-precision 7-resistor thin film network designed for demanding circuit applications. Encased in a ceramic SOIC-8 package, it offers a 20KΩ resistance per element with an exceptional ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for precision analog and digital systems. Its gull-wing termination and surface-mount design facilitate automated assembly, while the ceramic substrate enhances thermal performance and reliability.
