GUS-QS8A-03-3920-JA Description

The GUS-QS8A-03-3920-JA from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications in demanding electronic circuits. Encased in a 16-pin QSOP (Quarter Small Outline Package), this 392Ω resistor array offers a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating and 0.1W per resistor, it balances power handling with compact surface-mount (SMD) design, making it ideal for space-constrained PCB layouts. The gull-wing termination ensures reliable solder joints, while the 100V maximum voltage rating enhances durability in high-voltage environments.

GUS-QS8A-03-3920-JA Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm length/height).
• Isolated Resistors (ISOL): Each of the 8 resistors operates independently, enabling flexible circuit design.
• Robust Power Handling: 0.75W total dissipation (0.1W per resistor) suits medium-power applications.
• Wide Temperature Range: Operates reliably from -55°C to +125°C, derated up to 125°C.
• Automotive-Grade Alternatives: While not PPAP-certified, its performance parallels automotive-grade components.
