GUS-QS8A-01-42R2-FD Description

The GUS-QS8A-01-42R2-FD from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Housed in a 16-pin QSOP package with gull wing terminations, this surface-mount device offers a 42.2Ω resistance per resistor with a tight 1% tolerance and a low ±100ppm/°C temperature coefficient. Rated for 0.1W (1/10W) power dissipation per resistor and 0.75W (3/4W) total power, it operates reliably across a wide temperature range of -70°C to +125°C, with a maximum operating temperature of 125°C. Its compact dimensions (4.9mm x 6.02mm x 1.47mm) and isolated (ISOL) circuit design make it ideal for space-constrained PCB layouts.
