GQ8A022262FT Description

The GQ8A022262FT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding isolation and signal conditioning applications. Encased in a ceramic QSOP package, this 22.6KΩ resistor array offers 1% tolerance and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, it is engineered for reliability in precision circuits. The 16-pin gull-wing SMD termination and 4.9mm × 6.02mm compact footprint make it ideal for space-constrained designs.
