GQ8A027502CAT Description

The GQ8A027502CAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 8-resistor isolated network features a 75K Ohm resistance value with an ultra-tight 0.25% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Encased in a ceramic QSOP package, it offers superior thermal stability and durability. The 16-pin gull-wing SMD termination facilitates reliable surface mounting, while the 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating make it suitable for power-sensitive designs. With a maximum voltage rating of 100V, this component is ideal for precision analog and digital circuits.
