GUS-QS8A-01-3900-JB Description

The GUS-QS8A-01-3900-JB from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications in surface-mount circuits. With a 390Ω resistance value per resistor and a 5% tolerance, this 16-pin QSOP package delivers reliable performance in compact designs. The isolated (ISOL) circuit configuration ensures independent resistor operation, making it ideal for signal conditioning, voltage division, and impedance matching. Rated for 0.75W (3/4W) total power dissipation and 0.1W per resistor, it operates across a wide temperature range of -55°C to +125°C, with derated power handling up to 125°C. Its thin film technology ensures low noise and excellent stability, with a ±100ppm/°C temperature coefficient.

GUS-QS8A-01-3900-JB Features

• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), ideal for space-constrained PCBs.
• High Power Handling: 0.75W total power rating with 0.1W per resistor, superior to standard arrays in similar form factors.
