GS4B013920DBT Description

The GS4B013920DBT 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 392Ω resistance per element with an ultra-tight ±0.5% tolerance and a ±100ppm/°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 component is engineered for reliability in demanding circuits. Its gull-wing termination and 1.27mm pitch facilitate easy PCB integration, while the ceramic substrate enhances thermal performance.
