GQ8A039090DBT Description

The GQ8A039090DBT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding isolation and signal conditioning applications. Encased in a ceramic QSOP package, it offers a 909Ω resistance per element with an ultra-tight ±0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range (70°C to 125°C). The 16-pin gull-wing SMD configuration and 0.64mm terminal pitch facilitate compact PCB layouts, while its 0.75W total power rating (0.1W per resistor) supports robust performance in high-density circuits.

GQ8A039090DBT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±0.5%) for critical analog/digital interfaces.
• Ceramic QSOP Package: Enhances thermal dissipation and mechanical durability vs. plastic alternatives.
• Isolation-Centric Design (ISOL): Ideal for galvanic isolation in industrial controls or medical devices.
• Wide Voltage Rating (100V): Suitable for mixed-signal systems requiring voltage division or buffering.
• Non-Automotive (PPAP No): Optimized for commercial/industrial use, with non-RoHS compliance for legacy applications.
