GQ8A036982CAT Description

The GQ8A036982CAT 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 features a 69.8KΩ resistance per resistor with an ultra-tight ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a 70°C to 125°C operating range. The 16-pin gull-wing SMD design offers reliable surface-mount compatibility, while the 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for high-reliability circuits. Packaged in a tube, this non-automotive, non-PPAP component is ideal for precision analog and mixed-signal systems.

GQ8A036982CAT Features

• Isolation-Centric Design: Labeled "ISOL", optimized for galvanic isolation and noise-sensitive applications.
• Ceramic QSOP Case: Enhances thermal performance and mechanical durability vs. plastic alternatives.
• Thin Film Technology: Delivers superior accuracy (±0.25%) and low TCR (±25ppm/°C) for precision circuits.
