GQCA033321GT

GQCA033321GT Description

The GQCA033321GT 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 3.32KΩ resistance value and a tight 2% tolerance. Encased in a ceramic package, it offers superior thermal stability and reliability, with a temperature coefficient of ±25ppm/°C and a maximum operating temperature of 125°C. The 1W total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for high-performance circuits. Its gull-wing termination ensures secure surface-mount (SMD) assembly, while the QSOP package (8.66mm × 6.02mm × 1.47mm) provides compact integration for space-constrained designs.

GQCA033321GT Features

• Precision Thin Film Technology: Delivers stable performance with ±25ppm/°C TCR and 2% tolerance for accuracy-critical applications.
• Robust Ceramic Case: Enhances thermal dissipation and mechanical durability, ideal for harsh environments.
• Isolated Resistor Network (ISOL): 12 independent resistors reduce crosstalk, improving signal integrity in analog/digital systems.
• High Power Handling: 1W total power (0.1W per resistor) supports energy-efficient designs.
• Compact QSOP Package: Space-saving 24-pin gull-wing SMD footprint (6.02mm depth, 1.47mm height) for high-density PCBs.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, ensuring reliability in industrial settings.

GQCA033321GT Applications

• Signal Conditioning: Precision voltage dividers, feedback networks, and sensor interfaces in test/measurement equipment.
