GUS-QS8A-00-56R0-GF Description

The GUS-QS8A-00-56R0-GF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. This 8-resistor isolated network features a 56 Ohm resistance value with a tight 2% tolerance and a low ±250ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Packaged in a compact 16-pin QSOP (QSOP-16) case, it offers 0.75W (3/4W) total power rating (0.1W per resistor) and supports 100V maximum voltage, making it ideal for space-constrained designs requiring reliable signal conditioning or voltage division.

GUS-QS8A-00-56R0-GF Features

• Thin-Film Technology: Delivers superior accuracy, low noise, and long-term stability compared to thick-film alternatives.
• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk in sensitive analog/digital systems.
• High Power Density: 0.75W total power dissipation in a miniature 4.9mm × 6.02mm × 1.47mm footprint, optimizing PCB space.
• Robust Construction: Gull-wing SMD termination ensures secure mounting, while the QSOP package enhances thermal management.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, suitable for industrial and automotive-grade environments (though not PPAP/automotive-certified).
• Non-RoHS Compliant: May be preferred for legacy or specialized applications requiring leaded components.

GUS-QS8A-00-56R0-GF Applications

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor calibration in test/measurement equipment.
• Signal Isolation: Buffering and impedance matching in data acquisition systems or communication interfaces (e.g., RS-485).
• Power Management: Load balancing in DC-DC converters or power supply feedback loops.
• Industrial Controls: PLCs, motor drives, and instrumentation where temperature stability is critical.
• Legacy Electronics: Maintenance or upgrades of non-RoHS-compliant systems.
