GQCA034642DBT Description

The GQCA034642DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated resistors, each with a 46.4KΩ resistance value and an ultra-tight 0.5% tolerance. Encased in a ceramic package, it offers superior thermal stability and durability, with a ±25ppm/°C temperature coefficient and a maximum operating temperature of 125°C. The gull-wing termination ensures reliable surface-mount (SMD) compatibility, while the 1W total power rating (0.1W per resistor) makes it suitable for power-sensitive designs.
