GQ8A012801BBT Description

The GQ8A012801BBT 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 2.8KΩ 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 gull-wing SMD terminations for reliable surface mounting and delivers a total power rating of 0.75W (3/4W), with 0.1W (1/10W) per resistor. Its isolated (ISOL) circuit design and 100V maximum voltage rating make it suitable for precision analog and mixed-signal circuits.

GQ8A012801BBT Features

• High Precision: 0.1% tolerance and ±100ppm/°C TCR for stable performance in critical applications.
• Robust Construction: Ceramic case ensures durability and thermal stability.
• Space-Efficient: Compact QSOP package (4.9mm x 6.02mm x 1.47mm) with 0.64mm pitch for high-density PCB layouts.
• Isolated Design: Independent resistors (ISOL configuration) prevent crosstalk in multi-channel systems.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power.
• Surface-Mount Ready: Gull-wing terminations facilitate automated assembly processes.
