GQ8A031690JGT Description

The GQ8A031690JGT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications requiring stable resistance values and tight tolerances. Encased in a ceramic QSOP package, this 16-pin surface-mount device (SMD) offers a 169Ω resistance per resistor with a 5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring reliable operation across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it is engineered for demanding circuits requiring isolation (ISOL) and minimal thermal drift. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while the ceramic case enhances durability and heat dissipation.

GQ8A031690JGT Features

• Thin-Film Technology: Delivers superior stability, low noise, and precision compared to thick-film alternatives.
• Ceramic QSOP Package: Provides excellent thermal performance and mechanical robustness for harsh environments.
• Isolated Resistor Network (ISOL): Each resistor operates independently, ideal for signal isolation and multi-channel applications.
• Wide Operating Range: Functions reliably from 70°C to 125°C with derated power, suited for industrial and automotive-adjacent systems (though not PPAP/automotive-certified).
• Compact & Reliable: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) dimensions with tight tolerances (±0.1mm height/length, ±0.2mm depth) ensure consistent PCB fit.
• Non-RoHS: May be preferred for legacy or specific industrial applications where RoHS compliance is not mandated.

GQ8A031690JGT Applications

This resistor network excels in:

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor interfaces requiring low TCR and tight tolerance.
• Isolation & Signal Conditioning: Multi-channel data acquisition systems, where independent resistors prevent crosstalk.
• Industrial Controls: PLCs, motor drives, and power supplies needing robust, temperature-stable components.
• Test & Measurement Equipment: Calibration circuits and instrumentation where long-term stability is critical.
• Legacy Electronics Repair: Non-RoHS compliance makes it suitable for maintaining older equipment.

Conclusion of GQ8A031690JGT

The GQ8A031690JGT stands out for its thin-film precision, ceramic-encased durability, and isolated resistor design, making it a top choice for engineers prioritizing performance in thermally challenging or noise-sensitive environments. While not automotive-grade, its wide temperature range, low TCR, and compact form factor cater to industrial, instrumentation, and high-reliability applications. For designs demanding stable resistance with minimal drift, this network offers a compelling balance of technical rigor and practical versatility.
