GS4B011581DCT Description

The GS4B011581DCT 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 1.58KΩ 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, it features gull-wing SMD terminations for reliable surface-mount assembly. With a 0.4W total power rating (0.05W per resistor) and a 100V maximum voltage rating, this component is engineered for precision analog and digital circuits. Its compact dimensions (4.9mm x 5.99mm x 1.45mm) and ±0.1mm height/length tolerances make it ideal for space-constrained designs.
