GQ8A014321DAT Description

The GQ8A014321DAT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding isolation circuit applications. Housed in a 16-pin QSOP ceramic package, it offers a 4.32KΩ resistance per resistor with an ultra-tight ±0.5% tolerance and a low ±100ppm/°C temperature coefficient. The device operates over a wide temperature range of 70°C to 125°C (derated) and can withstand 100V maximum voltage, making it suitable for high-reliability environments. Its 0.75W (3/4W) total power rating and 0.1W per resistor ensure robust performance in compact designs. The gull-wing termination and surface-mount (SMD) configuration facilitate easy PCB integration.
