GUS-QS8A-03-3320-GB Description

The GUS-QS8A-03-3320-GB 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 device offers a 332Ω resistance per resistor with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. Its 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits requiring isolation (denoted by "ISOL" circuit designator). The thin film technology provides superior accuracy and reliability compared to thick-film alternatives.

GUS-QS8A-03-3320-GB Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Compact QSOP Package: Measures 4.9mm (L) x 6.02mm (D) x 1.47mm (H) with ±0.1mm dimensional tolerances, ideal for space-constrained PCBs.
• Isolated Resistor Network: Independent resistors (non-bussed) enable flexible circuit design.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, with derated power up to 125°C.
• Robust Construction: Gull wing terminals and surface-mount design ensure secure PCB attachment.
• Non-Automotive/Non-PPAP: Optimized for industrial, telecom, and instrumentation use.
