GQ0A026652CAT Description

The GQ0A026652CAT 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 66.5kΩ resistance 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 125°C maximum operating temperature. The gull-wing termination ensures reliable surface-mount (SMD) assembly, while its 1W total power rating (0.1W per resistor) makes it suitable for power-sensitive circuits.
