GQ8A021101DT Description

The GQ8A021101DT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding isolation and signal conditioning applications. Housed in a 16-pin QSOP ceramic package, it offers a 1.1KΩ resistance per resistor with an ultra-tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The 0.75W (3/4W) total power rating and 100V maximum voltage rating make it suitable for high-reliability circuits. Its isolated (ISOL) circuit design minimizes crosstalk, while the ceramic case provides excellent thermal and mechanical robustness.

GQ8A021101DT Features

• Precision Thin Film Technology: Delivers high accuracy (±0.5%) and low TCR (±50ppm/°C) for stable performance.
• Robust Ceramic Package: Enhances thermal dissipation and durability in harsh environments.
• Isolated Resistor Network (ISOL): Reduces interference in multi-channel systems.
• High Power Handling: 0.1W per resistor (0.75W total) with derating up to 125°C.
• Surface-Mount Gull Wing Terminals: Ensures reliable solder joints with a 0.64mm pitch for compact PCB layouts.
• Non-Automotive, Non-PPAP: Ideal for industrial and instrumentation applications.
