GQ8A033402GT Description

The GQ8A033402GT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a ceramic QSOP package, it offers 34K Ohm resistance per resistor with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -70°C to +125°C. The isolated (ISOL) circuit design provides independent resistors, making it ideal for circuits requiring electrical separation. With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, this 16-pin gull-wing SMD component is engineered for reliability in demanding environments.

GQ8A033402GT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±25ppm/°C) for sensitive analog/digital circuits.
• Robust Ceramic Package: Enhances thermal performance and mechanical durability compared to plastic alternatives.
• Isolated Resistor Network: Each of the 8 resistors operates independently, eliminating crosstalk in multi-channel systems.
• High Power Handling: 0.1W per resistor (0.75W total) derated up to 125°C, suitable for power-sensitive designs.
• Compact QSOP-16 Footprint: 4.9mm × 6.02mm × 1.47mm with ±0.1mm dimensional tolerances, enabling high-density PCB layouts.
• Gull Wing Termination: Ensures reliable surface-mount soldering with a 0.64mm pitch for automated assembly.

GQ8A033402GT Applications

• Industrial Control Systems: Signal conditioning, voltage dividers, and feedback networks in PLCs and sensors.
• Medical Electronics: Precision instrumentation where stable resistance values are critical (e.g., patient monitors).
• Automotive (Non-Automotive Rated): Engine control units (ECUs) and infotainment systems requiring isolation.
• Telecommunications: Line termination and impedance matching in high-frequency circuits.
• Test & Measurement Equipment: Calibration references and analog front-end circuits.

Conclusion of GQ8A033402GT

The GQ8A033402GT stands out for its ceramic isolation, thin-film precision, and compact power efficiency, making it a superior choice over standard epoxy-coated networks. While not PPAP or automotive-qualified, its wide temperature range and high voltage tolerance cater to industrial and medical applications demanding long-term reliability. Engineers will appreciate its balance of performance, size, and cost in space-constrained, high-accuracy designs.
