GS4B022872DDT Description

The GS4B022872DDT 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 28.7KΩ resistance per resistor with an ultra-tight ±0.5% tolerance and a low ±50ppm/°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 demanding environments. Its gull-wing termination and surface-mount design facilitate automated assembly, while the ceramic substrate enhances thermal performance and durability.
