GUS-QS0B-03-6190-FF Description

The GUS-QS0B-03-6190-FF from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 19-resistor array features a 619Ω resistance value per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Packaged in a 20-pin QSOP with gull-wing terminations, it offers a compact footprint (8.66mm × 6.02mm × 1.47mm) and is supplied in tubes for automated assembly. Rated for 1W total power dissipation (0.05W per resistor) and 100V maximum voltage, it combines precision with robustness in space-constrained designs.

GUS-QS0B-03-6190-FF Features

• High-Density Integration: 19 resistors in a QSOP package (20-pin) with 0.64mm terminal pitch, ideal for PCB space optimization.
• Precision Performance: Thin-film technology delivers ±1% tolerance and ±25ppm/°C TCR, critical for analog signal conditioning and voltage division.
• Wide Temperature Range: Operates reliably from -70°C to +125°C (derated power up to 125°C), suitable for industrial and automotive environments (though not PPAP/automotive-certified).
• Robust Construction: Gull-wing SMD terminations ensure secure mounting, while ±0.1mm height/length tolerances aid in consistent placement.
• Non-RoHS Compliance: Suitable for legacy or specialized applications where RoHS restrictions are not required.

GUS-QS0B-03-6190-FF Applications

• Signal Processing: Precision voltage dividers, DAC/ADC reference networks, and feedback circuits in test equipment.
• Industrial Controls: Sensor calibration, instrumentation amplifiers, and PLCs requiring stable resistance under thermal stress.
• Telecommunications: Impedance matching and termination in high-frequency RF modules.
• Legacy Systems: Maintenance or upgrades of non-RoHS-compliant electronics in military/aerospace (subject to ECCN EAR99).

Conclusion of GUS-QS0B-03-6190-FF

The GUS-QS0B-03-6190-FF excels in high-density, precision applications where thermal stability, compactness, and repeatability are paramount. Its thin-film construction and QSOP packaging make it a superior alternative to thicker-film networks or discrete resistors in space-sensitive designs. While not automotive-grade, its wide temperature range and 1W power handling cater to industrial, telecom, and legacy systems. Engineers will value its balance of performance and integration, particularly in analog circuitry requiring minimal drift over temperature.
