GQ0A0191R0JGT Description

The GQ0A0191R0JGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. This 10-resistor array features a 91Ω resistance per element with a 5% tolerance and a low ±100ppm/°C temperature coefficient, ensuring reliable performance across a -70°C to +125°C operating range. Housed in a 20-pin QSOP package with gull-wing SMD termination, it offers a compact 8.66mm × 6.02mm × 1.47mm footprint, ideal for space-constrained PCB designs. The ceramic case and isolated circuit design enhance thermal management and electrical isolation, while a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for moderate-power applications.

GQ0A0191R0JGT Features

• Thin-film technology: Delivers superior stability, low noise, and tight TCR performance.
• High-density integration: 10 resistors in a compact QSOP package (20 pins) with 0.64mm terminal pitch.
• Robust construction: Ceramic substrate ensures durability and efficient heat dissipation.
• Wide temperature range: Operates reliably from -70°C to +125°C (derated power above 70°C).
• Isolated design: Each resistor is electrically independent, reducing crosstalk in multi-channel circuits.
• SMD compatibility: Gull-wing termination simplifies automated assembly processes.

GQ0A0191R0JGT Applications

This resistor network excels in:

• Analog signal conditioning: Voltage dividers, feedback networks, and sensor interfaces in industrial controls.
• Medical electronics: Precision instrumentation where thermal stability is critical.
• Telecommunications: Impedance matching and filtering in RF modules.
• Automotive subsystems (non-AECQ): Non-safety-critical circuits like infotainment or lighting controls.
• Test & measurement equipment: Calibration circuits requiring long-term drift resistance.

Conclusion of GQ0A0191R0JGT

The GQ0A0191R0JGT combines thin-film precision, compact packaging, and isolated design to address demanding circuit requirements.
