GQ0A011131CT Description

The GQ0A011131CT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP (Quarter Small Outline Package) device features 10 isolated resistors, each with a 1.13KΩ resistance, a tight ±0.25% tolerance, and a ±100ppm/°C temperature coefficient. Encased in a ceramic package, it offers superior thermal stability and durability, with a maximum operating temperature of 125°C. The gull-wing termination ensures reliable surface-mount (SMD) assembly, while the 0.1W power rating per resistor (1W total) and 100V maximum voltage rating make it suitable for precision analog and digital circuits.

GQ0A011131CT Features

• High Precision: ±0.25% tolerance and ±100ppm/°C TCR ensure minimal drift in critical applications.
• Robust Construction: Ceramic case and thin-film technology provide excellent thermal and long-term stability.
• Isolated Design: 10 independent resistors (ISOL circuit designator) prevent crosstalk in multi-channel systems.
• Space-Efficient: Compact QSOP package (8.66mm x 6.02mm x 1.47mm) with 0.64mm pitch for high-density PCB layouts.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, ideal for industrial environments.
• Non-Automotive: Not PPAP-capable, but suited for industrial, medical, and test/measurement equipment.

GQ0A011131CT Applications

• Signal Conditioning: Precision voltage dividers, DAC/ADC reference networks.
• Isolation Circuits: Buffering and impedance matching in communication interfaces (RS-485, CAN).
• Medical Electronics: Patient monitoring systems where low drift and reliability are critical.
• Test & Measurement: Calibration equipment, sensor interfaces, and precision instrumentation.
• Industrial Controls: PLCs, motor drives, and power supply feedback loops requiring stable resistance.
