GQ8A032490CBT Description

The GQ8A032490CBT 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 249Ω resistance value with an ultra-tight 0.25% 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 0.1W (1/10W) power rating per resistor and a total power handling of 0.75W (3/4W). The gull-wing termination and surface-mount design facilitate automated assembly, while the 100V maximum voltage rating makes it suitable for high-reliability circuits.
