GUS-QS8A-03-5232-GB Description

The GUS-QS8A-03-5232-GB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount (SMD) configurations. This 8-resistor isolated network features a 52.3KΩ resistance value per resistor with a tight 2% tolerance and an ultra-stable ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range of -70°C to +125°C. Housed in a 16-pin QSOP (Quarter-Small Outline Package), it offers a compact footprint (4.9mm length × 6.02mm depth × 1.47mm height) with gull-wing terminations for secure PCB mounting. The 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating make it suitable for moderate-power applications, while its 100V maximum voltage rating ensures robustness in demanding circuits.

GUS-QS8A-03-5232-GB Features

• Precision Thin Film Technology: Delivers low noise, high stability, and excellent TCR performance (±25ppm/°C).
• Isolated Circuit Design (ISOL): Each resistor operates independently, ideal for signal isolation or multi-channel applications.
• Compact QSOP Package: Space-saving 0.64mm terminal pitch and 1.63mm seated height enable high-density PCB layouts.
• Wide Operating Range: Reliable performance from -70°C to +125°C (derated power up to 125°C).
• Robust Construction: Gull-wing leads enhance mechanical stability and solderability in automated assembly.
• Non-Automotive/Non-PPAP: Suitable for industrial, telecom, and instrumentation use (not automotive-qualified).

GUS-QS8A-03-5232-GB Applications

This resistor network excels in:

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor interfaces requiring tight tolerance (±2%) and low TCR.
• Signal Conditioning: Isolation buffers in data acquisition systems or medical devices.
• Telecom & Networking Equipment: Line termination, impedance matching, and RF modules.
• Test & Measurement Instruments: Calibration circuits and reference voltage generation.
• Industrial Controls: PLCs and motor drives where temperature stability is critical.
