GQ8A014222BT Description

The GQ8A014222BT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 8-resistor array features a 42.2K Ohm resistance per element with an ultra-tight 0.1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring exceptional stability across a wide temperature range (70°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-reliability circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its 100V maximum voltage rating enhances versatility in various voltage-divider and signal-conditioning applications.
