GQ0A032802GT

GQ0A032802GT Description

The GQ0A032802GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance and low thermal drift. This 20-pin QSOP (Quarter Small Outline Package) device features 10 isolated resistors, each with a 28K Ohm resistance, 2% tolerance, and a ±25ppm/°C temperature coefficient. Encased in a ceramic package, it offers superior thermal stability and durability in harsh environments. With a 1W total power rating (0.1W per resistor) and a maximum operating temperature of 125°C, it is engineered for reliability in demanding circuits. The gull-wing termination ensures secure surface-mount (SMD) assembly, while the 100V maximum voltage rating makes it suitable for high-voltage isolation applications.

GQ0A032802GT Features

• Precision Thin Film Technology: Delivers low noise and excellent stability for sensitive analog/digital circuits.
• Isolated Resistor Network (ISOL): Each of the 10 resistors is electrically isolated, ideal for multi-channel signal conditioning.
• Ceramic QSOP Package: Enhances thermal dissipation and mechanical robustness compared to plastic alternatives.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, ensuring performance in elevated temperatures.
• Low TCR (±25ppm/°C): Minimizes resistance drift across temperature variations, critical for precision instrumentation.
• Compact Dimensions: 8.66mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm), saving PCB space.

GQ0A032802GT Applications

This resistor network excels in:

• Industrial Automation: Signal isolation in PLCs, sensor interfaces, and ADC/DAC circuits.
• Medical Electronics: Patient monitoring systems where precision and reliability are paramount.
• Telecommunications: Impedance matching and termination in high-frequency RF modules.
• Automotive (Non-Automotive Rated): Prototyping or non-safety-critical systems requiring stable resistance.
• Test & Measurement Equipment: Calibration networks and voltage dividers with minimal drift.

Conclusion of GQ0A032802GT

The GQ0A032802GT stands out for its ceramic-encased isolation, thin-film accuracy, and compact QSOP footprint, making it a superior choice over plastic-packaged networks in high-temperature or precision-critical designs. While not PPAP or automotive-qualified, its low TCR, high voltage tolerance, and robust construction cater to industrial, medical, and telecom applications demanding long-term stability. Engineers seeking a reliable, space-efficient resistor network for isolation or signal conditioning will find this model optimally balanced for performance and durability.
