GQ8B011021FFT

GQ8B011021FFT Description

The GQ8B011021FFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 15-resistor array features a 1.02KΩ resistance per element with a tight 1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. Housed in a 16-pin QSOP ceramic package, it offers a 0.75W (3/4W) total power rating (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for demanding circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case enhances thermal and mechanical durability.
