GQ8A013921CAT Description

The GQ8A013921CAT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding isolation and signal conditioning applications. Housed in a 16-pin QSOP ceramic package, it features 3.92KΩ resistance per element with an ultra-tight ±0.25% tolerance and ±100ppm/°C temperature coefficient, ensuring stability across a wide temperature range (70°C to 125°C). The 0.75W (3/4W) total power rating and 100V maximum voltage rating make it suitable for high-reliability circuits. Its gull-wing termination and surface-mount design facilitate compact PCB layouts in space-constrained environments.
