GQ8A011471CAT Description

The GQ8A011471CAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding circuit isolation and signal conditioning applications. This 8-resistor network features a 1.47KΩ resistance per element with an ultra-tight 0.25% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. Housed in a 16-pin QSOP ceramic package, it offers superior thermal stability and durability in harsh environments. The isolated (ISOL) circuit design allows independent resistor operation, making it ideal for precision analog and digital systems. With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, this component is engineered for reliability in high-performance electronics.
