GQ8A033482JGT Description

The GQ8A033482JGT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications requiring stable resistance values and low thermal drift. Encased in a ceramic QSOP package, this 16-pin surface-mount device (SMD) offers a 34.8KΩ resistance per resistor with a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, it is engineered for demanding circuits requiring isolation (denoted by the ISOL circuit designator). The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while the ceramic case enhances thermal stability and durability.

GQ8A033482JGT Features

• Thin-film technology: Delivers superior accuracy and stability compared to thick-film alternatives.
• High power handling: 0.1W per resistor (0.75W total) with derating up to 125°C, ideal for power-sensitive designs.
• Low TCR (±25ppm/°C): Minimizes resistance drift under thermal stress, critical for precision analog circuits.
• Ceramic QSOP package: Provides excellent heat dissipation and mechanical robustness in harsh environments.
• Isolated design (ISOL): Ensures independent resistor performance, reducing crosstalk in multi-channel systems.
• Compact dimensions (4.9mm x 6.02mm x 1.47mm): Saves board space in high-density layouts.

GQ8A033482JGT Applications

This resistor network excels in:

• Industrial automation: Signal conditioning, PLCs, and sensor interfaces requiring stable resistance.
• Medical electronics: Precision instrumentation where low thermal drift is critical.
• Telecommunications: RF modules and filtering circuits benefiting from isolated thin-film resistors.
• Automotive (non-AECQ): Non-safety-critical systems like infotainment or climate control.
• Test & measurement equipment: Calibration circuits and voltage dividers demanding tight tolerances.
