GQ8B0190R9GT Description

The GQ8B0190R9GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors, each with a 90.9 Ω resistance value and a tight 2% tolerance, ensuring consistent performance in demanding circuits. The network operates within a wide temperature range of 70°C to 125°C (derated) and can withstand up to 125°C at full load, making it suitable for environments with thermal stress. Its ceramic case and thin-film technology provide excellent stability, low noise, and a ±100ppm/°C temperature coefficient, critical for analog and signal-processing applications.

GQ8B0190R9GT Features

• High Power Handling: Delivers 0.75W (3/4W) total power (0.05W per resistor), ideal for power-sensitive designs.
• Precision Engineering: ±0.1mm height/length tolerances and gull-wing termination ensure reliable surface-mount assembly.
• Robust Construction: Ceramic substrate enhances thermal conductivity and mechanical durability.
• Voltage Resilience: Supports up to 100V, suitable for industrial and automotive-grade circuits (though not PPAP/automotive-certified).
• Compact Footprint: 4.9mm x 6.02mm x 1.47mm dimensions optimize space-constrained PCBs.
• Non-RoHS (EU) compliance may cater to legacy or specialized industrial systems.

GQ8B0190R9GT Applications

This resistor network excels in:

• Signal Conditioning: Precision voltage dividers, ADC/DAC interfaces.
