GUS-QS8A-01-2702-JB Description

The GUS-QS8A-01-2702-JB 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 27KΩ resistors with a 5% tolerance and a ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating and 0.1W per resistor, it delivers reliable power handling in compact designs. The gull-wing termination and 0.64mm pitch facilitate easy soldering and high-density layouts, while the 100V maximum voltage rating makes it suitable for industrial and instrumentation circuits.

GUS-QS8A-01-2702-JB Features

• Thin-Film Technology: Offers superior stability, low noise, and tight TCR (±100ppm/°C) compared to thick-film alternatives.
• Isolated Resistors (ISOL): Each of the 8 resistors operates independently, ideal for signal isolation or multi-channel applications.
• Robust Power Handling: 0.75W total dissipation (0.1W per resistor) at 125°C maximum operating temperature, derated for high-temperature environments.
• Compact QSOP Package: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) footprint with a 1.63mm seated height, optimizing space in dense PCBs.
• Automated Assembly-Friendly: Gull-wing leads and tube packaging ensure compatibility with pick-and-place systems.
• Non-Automotive (PPAP No): Suitable for industrial, telecom, and test equipment where automotive certification isn’t required.

GUS-QS8A-01-2702-JB Applications

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor conditioning in measurement equipment.
• Signal Isolation: Multi-channel data acquisition systems or ADC/DAC interfaces requiring independent resistor paths.
• Power Management: Load sharing or current limiting in power supplies and DC-DC converters.
• Industrial Controls: PLCs, motor drives, and instrumentation where temperature stability is critical.
• Telecom Infrastructure: RF modules and baseband processing requiring low-noise, stable resistance values.
