GQCA031273GGT Description

The GQCA031273GGT 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 package integrates 12 isolated resistors, each rated at 127KΩ with 2% tolerance and a ±25ppm/°C temperature coefficient. Encased in a ceramic housing, it offers superior thermal stability and durability, making it suitable for demanding environments. With a 1W total power rating (0.1W per resistor) and a maximum operating temperature of 125°C, this network is engineered for reliability in compact, surface-mount designs. Its gull-wing termination ensures secure PCB mounting, while the 100V maximum voltage rating accommodates moderate power applications.

GQCA031273GGT Features

• Precision Thin Film Technology: Delivers stable resistance with ±25ppm/°C TCR, ideal for analog signal conditioning.
• Isolated Resistor Network (ISOL): 12 independent resistors in a QSOP-24 package, reducing board space versus discrete components.
• High-Temperature Performance: Operates from 70°C to 125°C with derated power, ensuring reliability in thermal stress conditions.
• Robust Ceramic Case: Enhances mechanical strength and heat dissipation compared to polymer-based alternatives.
• Surface-Mount Design: Gull-wing leads with 0.64mm pitch facilitate automated assembly and high-density layouts.
