GS4B021912BBT Description

The GS4B021912BBT from TT Electronics/IRC is a high-precision 7-resistor thin film network designed for demanding circuit applications. Encased in a ceramic SOIC-8 package, it offers a 19.1KΩ resistance per resistor with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. Rated for 0.4W total power dissipation (0.05W per resistor) and 100V maximum voltage, this surface-mount (SMD) network is ideal for precision analog and digital systems. Its gull-wing termination and 1.27mm pitch facilitate reliable PCB assembly, while the ceramic substrate enhances thermal performance and durability.
