GQ0A014021GT

GQ0A014021GT Description

The GQ0A014021GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and tight tolerances. This 20-pin QSOP package features 10 isolated resistors, each with a 4.02KΩ resistance and a 2% tolerance, ensuring consistent performance in demanding circuits. The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) integration, while the ±100ppm/°C temperature coefficient guarantees minimal resistance drift across a wide operating range of -70°C to +125°C. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is engineered for durability in industrial and instrumentation systems.

GQ0A014021GT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistor Design (ISOL): Each of the 10 resistors operates independently, reducing crosstalk in multi-channel systems.
• Robust Ceramic Package: Enhances thermal management and mechanical strength compared to polymer-based arrays.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, suitable for harsh environments.
• Gull-Wing Termination: Facilitates automated PCB assembly and improves solder joint reliability.
• Compact QSOP Form Factor: 8.66mm × 6.02mm × 1.47mm dimensions with tight tolerances (±0.1mm length/height) save board space.

GQ0A014021GT Applications

Ideal for precision voltage dividers, feedback networks, and signal conditioning in:

• Industrial Control Systems: PLCs, motor drives, and sensor interfaces requiring stable resistance under thermal stress.
• Test & Measurement Equipment: Calibration circuits and data acquisition modules where low TCR (±100ppm/°C) is critical.
• Medical Electronics: Isolated signal paths in patient monitoring devices.
• Automotive (Non-Automotive Rated): Prototyping or non-safety-critical circuits due to its 125°C maximum temperature rating.

Conclusion of GQ0A014021GT

The GQ0A014021GT stands out for its combination of precision, isolation, and ruggedness, making it a superior choice over standard thick-film networks in applications demanding tight tolerances and thermal stability. While not PPAP or automotive-qualified, its ceramic construction and thin-film technology offer long-term reliability for industrial and instrumentation designs. Engineers will appreciate its balance of performance, compactness, and ease of integration in space-constrained, high-reliability systems.
