GQ0A014321GT Description

The GQ0A014321GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 20-pin QSOP (Quarter Small Outline Package) device features 10 isolated resistors, each with a 4.32KΩ resistance, 2% tolerance, and a ±100ppm/°C temperature coefficient. Encased in a ceramic package, it offers excellent thermal stability and durability, with 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 demanding circuits. Its gull-wing termination ensures secure surface-mount (SMD) assembly, while the QSOP package (8.66mm x 6.02mm x 1.47mm) provides compact integration.

GQ0A014321GT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistor Network (ISOL): Each of the 10 resistors is electrically isolated, enabling flexible circuit design.
• Robust Ceramic Case: Enhances thermal dissipation and mechanical strength compared to polymer-based arrays.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, ideal for industrial environments.
• Surface-Mount Gull Wing Terminals: Ensures reliable PCB connections with a 0.64mm pitch for high-density layouts.
• Non-Automotive (PPAP No): Optimized for general industrial, telecom, and instrumentation use.

GQ0A014321GT Applications

This resistor network excels in:

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