GS4B014420DDT Description

The GS4B014420DDT 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 442Ω resistance per element with an ultra-tight ±0.5% tolerance and a ±100ppm/°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 terminal pitch facilitate seamless PCB integration, while the ceramic substrate enhances thermal performance.

GS4B014420DDT Features
