GUS-QS8B-00-6491-J Description

The GUS-QS8B-00-6491-J is a high-performance thin-film resistor network from TT Electronics/IRC, designed for precision applications requiring stable resistance values and compact packaging. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors, each with a 6.49KΩ resistance (5% tolerance) and a ±250ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (70°C to 125°C). With a total power rating of 0.75W (3/4W) and 0.05W (1/20W) per resistor, it balances power dissipation and space efficiency. The gull-wing termination and surface-mount design facilitate automated assembly, while the 100V maximum voltage rating makes it suitable for low-to-medium voltage circuits.

GUS-QS8B-00-6491-J Features

• Thin-Film Technology: Delivers superior stability, low noise, and tight tolerance (±5%) compared to thick-film alternatives.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), ideal for space-constrained PCBs.
• High-Temperature Operation: Rated for 125°C maximum operating temperature, suitable for industrial and automotive-adjacent environments (though not PPAP/Automotive certified).
• Precision Gull Wing Terminals: Ensures reliable solder joints and compatibility with reflow processes.
• Non-RoHS Compliant: May be preferred for legacy or specialized applications requiring leaded soldering.
