GQ0A011152GT

GQ0A011152GT Description

The GQ0A011152GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. This 20-pin QSOP (Quarter-Small Outline Package) device features 10 isolated resistors, each with a 11.5KΩ resistance (2% tolerance) and a ±100ppm/°C temperature coefficient, ensuring reliable performance across a 70°C to 125°C derated power range. Encased in a ceramic package, it offers superior thermal stability and durability, with a 1W total power rating (0.1W per resistor). Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the 100V maximum voltage rating makes it suitable for moderate-voltage circuits.

GQ0A011152GT 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 independent, enabling flexible circuit design.
• Robust Ceramic Package: Enhances thermal dissipation and mechanical strength in harsh environments.
• Wide Operating Range: Functions reliably from -55°C to +125°C, with derated power up to 125°C.
• Compact QSOP-20 Form Factor: 8.66mm × 6.02mm × 1.47mm dimensions with tight tolerances (±0.1mm length/height, ±0.2mm depth) save board space.
• Automotive-Grade Alternatives: While this model is not PPAP or automotive-qualified, its performance parallels higher-tier industrial components.

GQ0A011152GT Applications

• Signal Conditioning: Ideal for op-amp feedback networks, DAC/ADC interfaces, and voltage dividers.
• Medical Electronics: Stable resistance values critical for patient monitoring equipment.
• Industrial Control Systems: Withstands temperature fluctuations in PLCs and sensor modules.
• Test & Measurement Equipment: Precision resistance networks for calibration circuits.
• Telecom Infrastructure: Used in line drivers and RF modules due to low parasitic effects.

Conclusion of GQ0A011152GT

The GQ0A011152GT excels in applications demanding precision, thermal resilience, and compactness. Its ceramic-encased thin-film design and isolated resistor configuration provide a competitive edge over polymer-based networks, particularly in environments with thermal stress or space constraints. While not RoHS-compliant, it remains a robust choice for industrial and medical designs where reliability outweighs regulatory requirements. Engineers seeking a cost-effective, high-performance resistor array will find this model a compelling solution.
