GQ8A021741FAT Description

The GQ8A021741FAT 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 1.74KΩ resistance value per resistor with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. Housed in a 16-pin QSOP ceramic package, it offers excellent thermal stability and durability, making it ideal for harsh environments. The 0.75W (3/4W) total power rating and 100V maximum voltage rating provide robust performance in compact designs.

GQ8A021741FAT Features

• Isolation-Centric Design: Labeled with "ISOL" circuit designator, optimized for isolation applications.
• High Power Handling: 0.1W per resistor (0.75W total) derated up to 125°C, superior to standard thin-film networks.
• Precision Thin-Film Technology: Delivers low TCR (±50ppm/°C) and 1% tolerance for accuracy-critical circuits.
• Ceramic QSOP Package: Enhances thermal dissipation and mechanical strength vs. plastic alternatives.
• Gull Wing Termination: Ensures reliable surface-mount (SMD) connectivity with a 0.64mm pitch.
• Non-Automotive, Non-PPAP: Suitable for industrial, telecom, and instrumentation use.
