GQ8A015111CAT Description

The GQ8A015111CAT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding isolation and signal conditioning applications. Encased in a ceramic QSOP package, it offers a 5.11KΩ resistance per resistor with an exceptional ±0.25% tolerance and ±100ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The 16-pin gull-wing SMD configuration and 0.64mm terminal pitch facilitate compact, high-density PCB layouts. With a 0.75W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network is engineered for reliability in precision analog and digital circuits.
