GS4B0173R2DDT Description

The GS4B0173R2DDT 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 73.2 Ω resistance per element with an ultra-tight ±0.5% tolerance and a ±100ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The device features gull-wing terminations for surface-mount (SMD) assembly, with a 0.4W total power rating (0.05W per resistor) and a 100V maximum voltage rating. Its compact dimensions (4.9mm x 5.99mm x 1.45mm) and ±0.1mm height/length tolerances make it suitable for space-constrained designs.
