GQCA0128R7GGT Description

The GQCA0128R7GGT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 24-pin QSOP (Quarter Small Outline Package) device integrates 12 isolated resistors, each with a 28.7Ω resistance value and a tight 2% tolerance. Encased in a ceramic substrate, it ensures superior thermal stability and durability, operating across a wide temperature range of -70°C to +125°C. With a thin-film technology foundation, it delivers excellent performance in ±100ppm/°C temperature coefficient and a 0.1W power rating per resistor (1W total). Its 100V maximum voltage rating and gull-wing termination make it ideal for surface-mount PCB designs requiring reliable, space-efficient solutions.
