GQ8A031802DT Description

The GQ8A031802DT 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 an 18K Ohm resistance value per element 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). Housed in a 16-pin QSOP ceramic package, it offers superior thermal stability and durability in harsh environments. The isolated (ISOL) circuit design prevents crosstalk, making it ideal for precision analog circuits. With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, this network balances power handling with compact surface-mount (SMD) gull-wing termination.
