GQ8A021101BBT Description

The GQ8A021101BBT 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 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). Housed in a ceramic QSOP package, it offers superior thermal stability and reliability in surface-mount (SMD) designs. With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, it is engineered for precision analog and digital circuits requiring minimal drift and high accuracy.

GQ8A021101BBT Features

• High Precision: 0.1% tolerance and ±50ppm/°C TCR for critical applications.
• Robust Construction: Ceramic case ensures excellent thermal dissipation and mechanical durability.
• Compact Design: 4.9mm × 6.02mm × 1.47mm QSOP package with 16 gull-wing terminals for high-density PCB layouts.
• Isolation-Centric: Designed with ISOL (isolated) circuit topology, ideal for reducing crosstalk in multi-channel systems.
• Wide Operating Range: Supports -55°C to +125°C with derated power up to 125°C.
• Thin-Film Technology: Delivers low noise and high stability compared to thick-film alternatives.
