GQ8B024220DCT Description

The GQ8B024220DCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 15 resistors, each with a 422Ω resistance value and a tight 0.5% tolerance, ensuring consistent performance in precision circuits. The network operates within a wide temperature range of 70°C to 125°C and delivers a total power rating of 0.75W (3/4W), with each resistor rated at 0.05W (1/20W). Its ceramic case and gull-wing termination provide robust mechanical stability and reliable solderability, while the ±50ppm/°C temperature coefficient ensures minimal resistance drift under thermal stress.
