GS4B031302DDT Description

The GS4B031302DDT from TT Electronics/IRC is a high-precision 7-resistor thin film network in an 8-pin SOIC package, designed for surface-mount applications. With a 13KΩ resistance per element, tight 0.5% tolerance, and low ±25ppm/°C temperature coefficient, this ceramic-based network ensures stable performance in demanding environments. Rated for 0.4W total power dissipation (0.05W per resistor) and 100V maximum voltage, it operates reliably across a 70°C to 125°C derated power range, making it suitable for precision analog and digital circuits. The gull-wing termination and 1.27mm pitch facilitate easy PCB integration, while the ceramic case enhances thermal and mechanical durability.

GS4B031302DDT Features

• Precision Thin Film Technology: Delivers ±0.5% tolerance and low TCR (±25ppm/°C) for stable resistance under thermal stress.
