GQ8A026982FT Description

The GQ8A026982FT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for isolation (ISOL circuit designator) in demanding electronic applications. Encased in a ceramic QSOP package, it offers a 69.8K Ohm resistance per resistor with a tight 1% tolerance and a low ±50ppm/°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 surface-mount (SMD) assembly, with a compact footprint of 4.9mm (L) × 6.02mm (D) × 1.47mm (H) and a 0.64mm terminal pitch. Its 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 compliant component is ideal for industrial and commercial use.
