GQ8A037682FAT Description

The GQ8A037682FAT 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 76.8K Ohm resistance per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. The device features 16 gull-wing terminals for reliable surface-mount assembly, with a compact footprint of 4.9mm (L) × 6.02mm (D) × 1.47mm (H). Its 0.75W (3/4W) total power rating and 100V maximum voltage rating make it suitable for high-density circuits requiring robust performance.

GQ8A037682FAT Features

• Isolation-Centric Design: Circuit designator "ISOL" ensures minimal crosstalk, ideal for precision analog/digital isolation.
• Ceramic QSOP Package: Enhances thermal management and durability compared to plastic alternatives.
• Thin Film Technology: Delivers superior accuracy and stability (±25ppm/°C) vs. thick-film networks.
• High Power Handling: 0.1W per resistor (0.75W total) supports sustained operation in power-sensitive applications.
• Automated Assembly-Friendly: Gull-wing termination and 0.64mm pitch enable seamless SMD placement.
• Non-Compliant to EU RoHS: Suitable for legacy or exempted industrial systems.
