GQ8A031003BAT Description

The GQ8A031003BAT 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 100K Ohm resistance value with an ultra-tight 0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -55°C to +125°C. Housed in a 16-pin QSOP ceramic package, it offers 0.75W (3/4W) total power dissipation and 0.1W per resistor, making it suitable for high-density PCB designs. The gull-wing termination and surface-mount (SMD) configuration facilitate automated assembly, while the isolated (ISOL) circuit design minimizes crosstalk in critical analog or digital circuits.
