GQ8B022550GDT Description

The GQ8B022550GDT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 15-resistor array features a 255Ω resistance value per resistor with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of -70°C to +125°C. Encased in a ceramic QSOP package, it offers excellent thermal stability and durability. The 16-pin gull-wing SMD termination facilitates reliable surface mounting, while the 0.05W (1/20W) power rating per resistor and 0.75W (3/4W) total power rating make it suitable for moderate-power circuits. With a maximum voltage rating of 100V, this network is ideal for bus termination, voltage division, and pull-up/down applications.
