GQ8A012101CAT Description

The GQ8A012101CAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 8-resistor array features a 2.1KΩ resistance value per resistor with an ultra-tight ±0.25% 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 0.75W (3/4W) total power dissipation and 0.1W (1/10W) per resistor, making it suitable for high-density PCB designs. The gull-wing termination and surface-mount (SMD) compatibility facilitate automated assembly, while its 100V maximum voltage rating enhances reliability in industrial and instrumentation circuits.
