GQ8A011741BT Description

The GQ8A011741BT from TT Electronics/IRC is a high-precision 8-resistor thin-film network designed for demanding isolation and signal conditioning applications. Encased in a ceramic QSOP package, it offers a 1.74KΩ resistance per resistor with an ultra-tight 0.1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. The device features 16 gull-wing terminals for reliable surface-mount assembly, with a compact footprint of 4.9mm (L) × 6.02mm (D) × 1.47mm (H). Its isolated (ISOL) circuit design and 100V maximum voltage rating make it suitable for precision analog and mixed-signal circuits.

GQ8A011741BT Features

• High Precision: 0.1% tolerance and ±100ppm/°C TCR for critical applications.
• Robust Construction: Ceramic case ensures thermal stability and durability.
• Power Handling: 0.1W per resistor (0.75W total) with derating up to 125°C.
• Space-Efficient: QSOP-16 package with 0.64mm pitch for high-density PCB layouts.
• Isolated Design: Independent resistors (ISOL) prevent cross-talk in sensitive circuits.
• Non-Automotive: Compliant with industrial standards (PPAP: No, EU RoHS: Not Compliant).

GQ8A011741BT Applications

Ideal for:

• Precision voltage dividers in test/measurement equipment.
• Signal isolation in medical devices and industrial control systems.
• Feedback networks for op-amps and ADCs/DACs.
• Impedance matching in RF and communication circuits.
• High-reliability systems where thermal drift and tolerance are critical.

Conclusion of GQ8A011741BT

The GQ8A011741BT excels in applications requiring high accuracy, thermal resilience, and compact form factors. Its ceramic construction and thin-film technology provide superior performance over polymer-based networks, while the isolated design minimizes interference.
