GQ8A011272BBT Description

The GQ8A011272BBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 16-pin QSOP device features 8 isolated resistors, each with a 12.7KΩ resistance and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy in critical circuits. Encased in a ceramic package, it offers superior thermal stability and durability, with a maximum operating temperature of 125°C and a ±100ppm/°C temperature coefficient. The gull-wing termination and surface-mount design facilitate reliable PCB integration, while the 0.75W (3/4W) total power rating (0.1W per resistor) supports robust performance in compact layouts.

GQ8A011272BBT Features

• Precision Performance: 0.1% tolerance and ±100ppm/°C TCR for stable operation in temperature-varying environments.
• Isolated Circuit Design: 8 independent resistors (ISOL configuration) prevent cross-talk in sensitive analog/digital systems.
• High Power Handling: 0.75W total dissipation (0.1W per resistor) exceeds typical network ratings for improved reliability.
• Robust Construction: Ceramic case ensures mechanical strength and thermal resistance (70–125°C derated range).
• Compact & Compatible: QSOP package (4.9mm × 6.02mm × 1.47mm) with 0.64mm pitch, ideal for high-density PCBs.
• Non-Automotive: Suitable for industrial, medical, and telecom applications requiring precision without PPAP compliance.
