GUS-QS8B-03-4641-JF Description

The GUS-QS8B-03-4641-JF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. This 16-pin QSOP (Quarter-Small Outline Package) device integrates 15 resistors, each with a 4.64KΩ resistance value and a tight ±5% tolerance, ensuring reliable signal conditioning and voltage division. With a 0.75W (3/4W) total power rating and 0.05W per resistor, it delivers robust performance in compact designs. The thin-film technology provides excellent stability, with a low ±25ppm/°C temperature coefficient, making it ideal for environments with fluctuating thermal conditions.

GUS-QS8B-03-4641-JF Features

• High-Density Integration: 15 resistors in a 4.9mm × 6.02mm × 1.47mm QSOP package, optimized for space-constrained PCBs.
• Precision Performance: ±5% tolerance and ±25ppm/°C TCR ensure minimal drift under thermal stress.
• Robust Power Handling: 0.75W total power dissipation (0.05W per resistor) with a 100V maximum voltage rating.
• Wide Temperature Range: Operates from 70°C to 125°C, suitable for industrial and automotive-grade applications (though not PPAP/automotive certified).
• Surface-Mount Gull Wing Terminals: Ensures secure 0.64mm pitch soldering for high-reliability assemblies.
• Non-RoHS Compliant: May be preferred for legacy or specific industrial systems requiring leaded components.
