GQ8A015490BBT Description

The GQ8A015490BBT 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 549Ω resistance value per resistor with an ultra-tight 0.1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a 16-pin QSOP ceramic package, it offers 0.75W (3/4W) total power dissipation and 0.1W per resistor, making it suitable for high-density PCB designs. The gull-wing termination and surface-mount (SMD) compatibility facilitate automated assembly, while its 100V maximum voltage rating enhances reliability in industrial and instrumentation circuits.

GQ8A015490BBT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog circuits.
• Isolation-Centric Design (ISOL): Ideal for applications requiring signal separation or voltage division.
• Robust Ceramic Package: Ensures thermal endurance and mechanical durability in harsh environments.
• Compact QSOP Form Factor: 4.9mm × 6.02mm × 1.47mm dimensions with ±0.1mm length/height tolerances for space-constrained layouts.
