GQ0A011203GT Description

The GQ0A011203GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance and isolation. This 20-pin QSOP package integrates 10 isolated resistors, each rated at 120KΩ with a 2% tolerance and a ±100ppm/°C temperature coefficient. The ceramic case ensures excellent thermal stability, supporting operation from 70°C to 125°C at derated power. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, it suits demanding circuits like signal conditioning and isolation. The gull-wing termination and surface-mount design (6.02mm x 8.66mm footprint) enable compact PCB layouts. Packaged in a tube, it’s ideal for prototyping and medium-scale production.

GQ0A011203GT Features

• Precision Thin Film Technology: Delivers low noise and high stability (±100ppm/°C) for sensitive analog circuits.
• Isolated Resistors (ISOL): 10 independent 120KΩ resistors prevent crosstalk, critical for multi-channel systems.
• Robust Ceramic Package: Enhances thermal dissipation and mechanical durability vs. polymer-based arrays.
• High Power Density: 1W total dissipation (0.1W/resistor) in a compact QSOP form factor.
• Automation-Friendly: Gull-wing leads (0.64mm pitch) simplify pick-and-place assembly.
• Wide Temp Range: Operates up to 125°C, suitable for industrial and telecom environments.
