GS7B033920FCT Description

The GS7B033920FCT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 14-pin narrow SOIC device features 13 bussed resistors with a 392Ω resistance value and a tight ±1% absolute tolerance, ensuring reliable performance in demanding circuits. Built with thin-film technology, it offers excellent stability with a low ±25ppm/°C temperature coefficient, making it ideal for environments with fluctuating temperatures. The SOIC package provides a compact footprint (8.66mm × 5.99mm × 1.45mm) with gull-wing terminations for easy surface-mount assembly. Rated for 0.7W total power dissipation (0.05W per resistor) and 100V maximum voltage, it operates reliably across a 70°C to 125°C derated power range, with a 125°C maximum operating temperature.
