GUS-QS8A-03-1333-JB Description

The GUS-QS8A-03-1333-JB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package features 8 isolated resistors, each with a 133K Ohm resistance and a 5% tolerance, ensuring reliable signal conditioning and voltage division. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it supports moderate power dissipation while maintaining stability across a wide temperature range (70°C to 125°C). The ±25ppm/°C temperature coefficient minimizes resistance drift, making it suitable for environments requiring thermal consistency. Its gull-wing termination and 0.64mm terminal pitch facilitate easy soldering and high-density board layouts.

GUS-QS8A-03-1333-JB Features

• Thin-Film Technology: Delivers superior accuracy, low noise, and long-term stability compared to thick-film alternatives.
• Isolated Resistors (ISOL): Each of the 8 resistors operates independently, ideal for multi-channel isolation.
• High Voltage Rating: Supports up to 100V, suitable for industrial and instrumentation circuits.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), optimizing space in constrained designs.
• Robust Construction: Withstands 125°C maximum operating temperature, ensuring reliability in harsh conditions.
• Non-Automotive/Non-PPAP: Tailored for general industrial, telecom, and consumer electronics.
