GUS-QS0B-03-1331-G Description

The GUS-QS0B-03-1331-G from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in compact surface-mount assemblies. This 20-pin QSOP package integrates 19 resistors, each with a 1.33KΩ resistance value and a tight 2% tolerance, ensuring reliable signal conditioning and voltage division. With a ±25ppm/°C temperature coefficient, it delivers stable performance across a wide operating range of -70°C to +125°C, making it suitable for demanding environments. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating further enhance its robustness in circuit designs.

GUS-QS0B-03-1331-G Features

• Precision Thin Film Technology: Offers low noise and high stability for sensitive analog/digital circuits.
• Compact QSOP Package: 8.66mm × 6.02mm × 1.47mm dimensions with gull-wing terminations for space-constrained PCB layouts.
• High Power Handling: 1W total dissipation (distributed across 19 resistors) outperforms similar networks in power density.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, ideal for industrial and automotive-adjacent applications (though not PPAP/automotive-certified).
• Strict Tolerances: ±0.1mm height/length and ±0.2mm depth mechanical tolerances ensure consistent mounting compatibility.

GUS-QS0B-03-1331-G Applications

• Signal Conditioning: Precision voltage dividers in sensor interfaces (e.g., thermocouples, strain gauges).
• Medical Electronics: Patient monitoring systems requiring stable resistance values under thermal stress.
• Test & Measurement Equipment: Calibration circuits where low TCR (±25ppm/°C) minimizes drift.
• Industrial Controls: PLCs and motor drivers benefiting from the 100V rating and thin-film reliability.
• Aerospace Avionics: Non-RoHS compliant version suits legacy systems where lead-free alternatives are unsuitable.
