GUS-QS8A-03-1302-GA Description

The GUS-QS8A-03-1302-GA 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 features 8 isolated resistors, each with a 13KΩ resistance value and a tight 2% tolerance, ensuring consistent performance in signal conditioning, voltage division, and impedance matching applications. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it supports reliable operation in compact, high-density PCB layouts. The ±25ppm/°C temperature coefficient and 125°C maximum operating temperature make it suitable for environments with thermal fluctuations.

GUS-QS8A-03-1302-GA Features

• Thin-Film Technology: Delivers superior stability, low noise, and high accuracy compared to thick-film alternatives.
• Isolated Resistors (ISOL): Each of the 8 resistors operates independently, providing design flexibility for complex circuits.
• Gull Wing Termination: Ensures secure surface-mount (SMD) attachment with a 0.64mm terminal pitch for high-density assemblies.
• Robust Power Handling: 0.75W total power dissipation and 100V maximum voltage rating enhance reliability in power-sensitive applications.
• Compact Dimensions: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with a 1.63mm seated height, ideal for space-constrained designs.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, ensuring performance in industrial and automotive-adjacent systems (though not PPAP/Automotive certified).

GUS-QS8A-03-1302-GA Applications

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor interfaces requiring tight tolerance (±2%) and low TCR (±25ppm/°C).
• Communication Systems: Signal conditioning in RF modules, filters, and impedance matching networks.
• Test & Measurement Equipment: High-accuracy instrumentation where resistor stability is critical.
• Medical Electronics: Isolated signal paths in diagnostic devices due to reliable thin-film construction.
• Industrial Controls: Durable performance in PLCs, motor drives, and power management systems.
