GUS-QS8A-03-1243-GB Description

The GUS-QS8A-03-1243-GB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount circuits. This 16-pin QSOP package features 8 isolated resistors, each with a 124KΩ resistance value and a tight 2% tolerance, ensuring reliable signal integrity and minimal deviation. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it delivers robust performance in compact designs. The ±25ppm/°C temperature coefficient and 125°C maximum operating temperature make it suitable for stable operation across a wide thermal range (70°C to 125°C derated). Its 100V maximum voltage rating and gull-wing termination ensure secure mounting and durability in demanding environments.

GUS-QS8A-03-1243-GB Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistor Network (ISOL): Each of the 8 resistors operates independently, reducing crosstalk.
• Compact QSOP Package: Measures 4.9mm (L) × 6.02mm (D) × 1.47mm (H), ideal for space-constrained PCBs.
• High Power Handling: 0.75W total (0.1W per resistor) outperforms similar networks in power density.
• Wide Temperature Range: Operates reliably from -55°C to 125°C (derated above 70°C).
• Automotive-Grade Alternatives: While not PPAP or automotive-certified, its robustness suits industrial and telecom applications.
