GS4B0184R5GDT Description

The GS4B0184R5GDT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package, designed for precision applications requiring stable thin-film resistance. With a 84.5Ω resistance value and ±2% absolute tolerance, this ceramic-based network ensures reliable performance in demanding environments. Its ±100ppm/°C temperature coefficient and 0.05W (1/20) power rating per resistor (0.4W total) make it suitable for circuits operating at 70°C to 125°C derated power range, with a maximum operating temperature of 125°C. The SOIC-C series construction offers robust surface-mount compatibility, featuring gull-wing terminations and a compact 4.9mm × 5.99mm × 1.45mm footprint (±0.1mm height/length tolerance).
