GQ8A031050DCT Description

The GQ8A031050DCT 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 a 105Ω resistance value with an ultra-tight ±0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The isolated (ISOL) circuit design allows independent resistor operation, making it ideal for precision analog and digital circuits. With a 0.75W total power rating (0.1W per resistor) and 100V maximum voltage rating, it balances power handling with compact surface-mount (SMD) gull-wing termination.
