GS4B011820DDT Description

The GS4B011820DDT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 7-resistor BUS-configuration array offers a 182Ω resistance per element with an ultra-tight ±0.5% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a ceramic SOIC-8 package with gull-wing SMD terminations, it combines 0.4W total power dissipation (0.05W per resistor) with a 100V maximum voltage rating, making it suitable for precision analog and digital circuits. The 4.9mm x 5.99mm x 1.45mm compact footprint and ±0.1mm dimensional tolerances ensure reliable PCB integration.
