GUS-QS0B-03-6982-DB Description

The GUS-QS0B-03-6982-DB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 19-resistor array features a 69.8KΩ resistance value with an ultra-tight 0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a compact 20-pin QSOP package with gull-wing terminations, it offers a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for high-reliability circuits. The device is non-automotive and non-PPAP compliant, with EU RoHS non-compliance noted.

GUS-QS0B-03-6982-DB Features

• Precision Thin Film Technology: Delivers excellent stability and low noise.
• High-Density Packaging: 8.66mm × 6.02mm × 1.47mm QSOP case optimizes board space.
• Robust Performance: ±0.1mm length/height tolerances and ±0.2mm depth tolerance ensure consistent mounting.
• Wide Operating Range: Functions reliably from -55°C to +125°C (derated power up to 125°C).
• Low TCR: ±25ppm/°C minimizes resistance drift under thermal stress.
• Gull-Wing Termination: Facilitates secure surface-mount (SMD) assembly.

GUS-QS0B-03-6982-DB Applications

• Precision Analog Circuits: Ideal for voltage dividers, feedback networks, and sensor interfaces in test equipment.
• Signal Conditioning: Used in data acquisition systems and medical instrumentation where accuracy is critical.
• Industrial Controls: Suitable for PLC modules and power management PCBs requiring stable resistance values.
• Telecommunications: Deployed in RF matching networks and filter circuits due to low parasitic effects.

Conclusion of GUS-QS0B-03-6982-DB

The GUS-QS0B-03-6982-DB excels in applications demanding high precision, compact size, and thermal stability. Its thin-film construction, tight tolerances, and robust QSOP package make it a superior choice over thicker-film or less stable alternatives. While not RoHS-compliant, its performance in industrial, telecom, and precision analog systems justifies its use in specialized designs. Engineers will appreciate its repeatability and power-handling capabilities in space-constrained, high-reliability environments.
