GUS-QS8A-03-5100-JA Description

The GUS-QS8A-03-5100-JA 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 integrates 8 isolated 510Ω resistors with a 5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it offers robust reliability in compact designs. The gull-wing termination and 0.64mm terminal pitch facilitate easy soldering and high-density mounting. Packaged in a tube, it is ideal for automated assembly processes.

GUS-QS8A-03-5100-JA Features

• Thin-Film Technology: Delivers superior accuracy and stability compared to thick-film alternatives.
• Isolated Circuit Design (ISOL): Each of the 8 resistors operates independently, enhancing flexibility in circuit design.
• High Power Density: 0.75W total dissipation in a compact 4.9mm × 6.02mm × 1.47mm footprint.
• Wide Temperature Range: Reliable performance from -70°C to +125°C, even at derated power.
• Low TCR (±25ppm/°C): Minimizes resistance drift under thermal stress.
• Automation-Friendly: Gull-wing leads and QSOP package optimize pick-and-place efficiency.
