GS4B012490DBT Description

The GS4B012490DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 7-resistor array features a 249Ω resistance value per resistor with a tight 0.5% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Encased in a ceramic SOIC-8 package, it offers 0.4W total power dissipation (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for precision analog and digital circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its compact dimensions (4.9mm x 5.99mm x 1.45mm) save board space.
