GQ8A0376R8DT Description

The GQ8A0376R8DT 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 offers a 76.8Ω resistance per element with an ultra-tight ±0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide -70°C to +125°C operating range. Rated for 0.1W per resistor (0.75W total power dissipation), it supports 100V maximum voltage, making it suitable for high-reliability circuits. The gull-wing SMD termination and 0.64mm pitch facilitate compact PCB layouts, while the ceramic case enhances thermal and mechanical robustness.
