GQCA031740GT

GQCA031740GT Description

The GQCA031740GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low temperature coefficients. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated resistors, each with a 174Ω resistance value and a tight 2% tolerance. Encased in a ceramic package, it offers superior thermal stability and durability, with a maximum operating temperature of 125°C and a derated power range of 70°C to 125°C. The gull-wing termination ensures reliable surface-mount (SMD) assembly, while its ±25ppm/°C temperature coefficient guarantees minimal resistance drift under varying thermal conditions.

GQCA031740GT Features
