GUS-QS8A-02-3902-JA Description

The GUS-QS8A-02-3902-JA 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 SMD termination, this 39K Ohm resistor array offers a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating range of -70°C to +125°C. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, it is engineered for reliability in demanding circuits. The isolated (ISOL) circuit design allows independent resistor operation, making it ideal for signal conditioning, voltage division, and impedance matching.

GUS-QS8A-02-3902-JA Features

• Thin Film Technology: Delivers superior accuracy, low noise, and excellent thermal stability compared to thick film alternatives.
• Compact QSOP Package: Measures 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm L/H, ±0.2mm D), saving PCB space.
• High Power Handling: 0.75W total dissipation (0.1W per resistor) supports energy-intensive applications.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, suitable for industrial and automotive environments (though not PPAP/automotive-certified).
• Isolated Design: Each resistor is electrically independent, enabling flexible circuit configurations.
• Gull Wing Termination: Ensures robust surface-mount attachment for high-vibration environments.
