GS4B016491CBT Description

The GS4B016491CBT 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 6.49KΩ resistance per element with an ultra-tight ±0.25% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -70°C to +125°C. Housed in a ceramic SOIC-8 package with gull-wing SMD termination, 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 rectangular ceramic construction enhances thermal performance, while the 1.27mm terminal pitch facilitates compact PCB layouts.
