GS4B034300CBT Description

The GS4B034300CBT from TT Electronics/IRC is a high-precision 7-resistor thin-film network in an 8-pin SOIC gull-wing SMD package. Designed for surface-mount applications, it features a 430Ω resistance per element with an ultra-tight ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range (70°C to 125°C). The ceramic case and thin-film technology provide excellent thermal performance and reliability, while the 0.4W total power rating (0.05W per resistor) suits compact, power-sensitive designs. Its 100V maximum voltage rating and BUS circuit designator make it ideal for signal conditioning and bus termination.
