GQ0A031000GCT Description

The GQ0A031000GCT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low temperature coefficients. This 10-resistor array features a 100Ω resistance per element with a tight 2% tolerance and a ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide operating temperature range of -70°C to +125°C. Housed in a 20-pin QSOP ceramic package, it offers 1W total power dissipation (0.1W per resistor) and 100V maximum voltage rating, making it suitable for demanding circuit isolation (ISOL) applications. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case enhances thermal stability and durability.

GQ0A031000GCT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistor Network (ISOL): Each resistor operates independently, minimizing crosstalk in multi-channel systems.
• Robust Ceramic Package: Withstands high temperatures and mechanical stress, ideal for harsh environments.
• Compact QSOP Form Factor: 8.66mm × 6.02mm × 1.47mm dimensions with ±0.1mm length/height tolerances ensure space-efficient PCB layouts.
• Wide Operating Range: Derated power up to 125°C ensures reliability in elevated-temperature applications.
• Gull-Wing SMD Termination: Simplifies automated assembly and inspection processes.

GQ0A031000GCT Applications

• Industrial Control Systems: Signal conditioning, voltage division, and feedback networks in PLCs and sensors.
• Medical Electronics: Precision instrumentation where low drift and high accuracy are critical.
• Telecommunications: Impedance matching and termination in high-frequency RF modules.
• Automotive (Non-Automotive Rated): Prototyping or non-safety-critical circuits requiring stable resistance.
• Test & Measurement Equipment: Calibration and reference circuits due to its low TCR and tight tolerance.

Conclusion of GQ0A031000GCT
