GUS-QS8A-02-2702-JB Description

The GUS-QS8A-02-2702-JB 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 27K Ohm resistance value per resistor with a 5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Packaged in a 16-pin QSOP (Quarter Small Outline Package) with gull-wing terminations, it offers a compact footprint (4.9mm x 6.02mm x 1.47mm) and a 0.64mm terminal pitch, making it ideal for space-constrained designs. The 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating provide robust operation in demanding circuits.

GUS-QS8A-02-2702-JB Features

• Thin-Film Technology: Delivers superior accuracy, low noise, and excellent long-term stability compared to thick-film alternatives.
• Isolated Resistors (ISOL): Each resistor operates independently, eliminating crosstalk and enabling flexible circuit design.
• High Power Density: 0.75W total power dissipation in a compact QSOP package, optimizing thermal management.
• Wide Temperature Range: Reliable performance from -70°C to +125°C, suitable for industrial and harsh environments.
