GS4B012802CBT Description

The GS4B012802CBT from TT Electronics/IRC is a high-precision 7-resistor thin film network designed for BUS circuit applications. Encased in a ceramic SOIC-8 package, it offers a 28KΩ resistance per element with an ultra-tight ±0.25% tolerance and a low ±100ppm/°C temperature coefficient. Rated for 0.4W total power dissipation (0.05W per resistor), it operates reliably across a wide temperature range of -70°C to +125°C, making it suitable for demanding environments. The gull-wing termination and surface-mount design ensure compatibility with automated assembly processes.
