GS4B022100DDT Description

The GS4B022100DDT from TT Electronics/IRC is a high-precision 7-resistor thin film network designed for surface-mount applications. Encased in a ceramic SOIC-8 package, it offers a 210Ω resistance per element with an ultra-tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range (70°C to 125°C). Rated for 0.4W total power dissipation (0.05W per resistor) and 100V maximum voltage, this BUS-designated network is ideal for precision analog and digital circuits. Its gull-wing termination and 1.27mm pitch facilitate reliable PCB assembly, while the ceramic substrate enhances thermal performance.
