GUS-QS8A-03-3242-JA Description

The GUS-QS8A-03-3242-JA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount configurations. This 16-pin QSOP package integrates 8 isolated resistors, each with a 32.4KΩ resistance value and a tight ±5% tolerance, ensuring reliable signal conditioning and voltage division. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it operates efficiently across a wide temperature range of 70°C to 125°C, derated for optimal performance. The device features a ±25ppm/°C temperature coefficient, enhancing stability in thermally dynamic environments. Its gull-wing termination and 0.64mm terminal pitch facilitate robust PCB mounting, while the compact 4.9mm x 6.02mm x 1.47mm footprint suits space-constrained designs.
