GQ8A024300JAT Description

The GQ8A024300JAT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision isolation circuits. Housed in a 16-pin QSOP ceramic package, it offers a 430Ω resistance per element with a 5% tolerance and ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The 0.75W (3/4W) total power rating and 0.1W per resistor make it suitable for demanding applications, while its 100V maximum voltage rating and gull-wing SMD termination ensure reliable surface-mount integration. The ceramic case enhances thermal stability, and the isolated (ISOL) circuit design provides flexibility in circuit configurations.
