GQ8A021101BT Description

The GQ8A021101BT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 8-resistor array features a 1.1KΩ resistance value per resistor with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Encased in a ceramic QSOP package, it offers superior thermal stability and durability. The 16-pin gull-wing SMD termination facilitates reliable surface mounting, while the 0.75W (3/4W) total power rating and 100V maximum voltage rating make it suitable for high-reliability circuits.

GQ8A021101BT Features

• Precision Thin Film Technology: Delivers high accuracy (±0.1%) and low TCR (±50ppm/°C) for critical analog/digital applications.
• Robust Ceramic Construction: Enhances thermal dissipation and mechanical strength in harsh environments.
• Compact QSOP Package: Measures 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm L/H, ±0.2mm D).
