GQ8A034530GFT Description

The GQ8A034530GFT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a ceramic QSOP package, it offers a 453Ω resistance per resistor with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The isolated (ISOL) circuit design provides independent resistors, making it ideal for signal conditioning and voltage division. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, it balances power handling and compactness (4.9mm × 6.02mm × 1.47mm). The gull-wing termination and 0.64mm pitch enable reliable surface-mount assembly in space-constrained designs.
