GQ0A028251CAT Description

The GQ0A028251CAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP (Quarter Small Outline Package) device features 10 isolated resistors, each with a 8.25KΩ resistance value and an ultra-tight ±0.25% tolerance. Encased in a ceramic package, it offers superior thermal stability and durability, with a ±50ppm/°C temperature coefficient and a maximum operating temperature of 125°C. The gull-wing termination ensures reliable surface-mount (SMD) compatibility, while the 0.1W (1/10) power rating per resistor and 1W total power rating make it suitable for precision analog and digital circuits.
