GUS-QS8A-02-1270-DC Description

The GUS-QS8A-02-1270-DC from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 8-resistor isolated network features a 127Ω resistance value per resistor with a tight 0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a compact 16-pin QSOP package with gull-wing terminations, it offers a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for high-density PCB designs.

GUS-QS8A-02-1270-DC Features

• Precision Thin Film Technology: Delivers superior accuracy (±0.5%) and low TCR (±50ppm/°C) for stable operation in thermal environments.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with a 0.64mm terminal pitch, ideal for space-constrained designs.
• Isolated Resistor Network (ISOL): Each of the 8 resistors is electrically isolated, providing design flexibility in signal conditioning and voltage division.
• Robust Power Handling: 0.75W total power dissipation (0.1W per resistor) and 125°C maximum operating temperature ensure reliability in high-stress applications.
• Surface-Mount Gull Wing Terminations: Facilitates automated PCB assembly and secure solder joints.
