GUS-QS8A-03-3900-JF Description

The GUS-QS8A-03-3900-JF from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Encased in a 16-pin QSOP package with gull wing terminations, this surface-mount device offers a 390Ω resistance per element with a 5% tolerance and a ±25ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power dissipation and 0.1W per resistor, it operates reliably across a wide temperature range of -70°C to +125°C, making it suitable for demanding environments. The isolated (ISOL) circuit design ensures individual resistor performance without crosstalk, while its compact dimensions (4.9mm x 6.02mm x 1.47mm) enable high-density PCB layouts.
