GUS-QS8A-03-1470-JF Description

The GUS-QS8A-03-1470-JF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 8-resistor isolated network features a 147Ω resistance value per resistor with a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Encased in a 16-pin QSOP (Quarter Small Outline Package), it offers a compact footprint with 4.9mm length, 6.02mm depth, and 1.47mm height, making it ideal for space-constrained designs. The gull-wing termination ensures reliable solder joints, while the 0.64mm terminal pitch facilitates automated assembly. Rated for 0.1W (1/10W) per resistor and 0.75W (3/4W) total power dissipation, it supports moderate power applications with a maximum voltage rating of 100V.

GUS-QS8A-03-1470-JF Features

• Thin-Film Technology: Delivers superior accuracy, low noise, and excellent thermal stability compared to thick-film alternatives.
• Isolated Circuit Design (ISOL): Each resistor operates independently, enhancing flexibility in circuit design.
• High-Temperature Resilience: Operates reliably up to 125°C, suitable for industrial and automotive environments (though not PPAP/automotive certified).
• Compact QSOP Package: Optimizes board space with a 1.63mm seated height and rectangular profile.
• Robust Power Handling: 0.75W total power rating ensures durability in demanding applications.
• Non-RoHS Compliant: Suitable for legacy or specialized systems where RoHS exemptions apply.
