GS4B028252DBT Description

The GS4B028252DBT 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 82.5KΩ 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 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.
