GUS-QS8B-01-1870-D Description

The GUS-QS8B-01-1870-D from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 15 resistors, each with a resistance value of 187Ω and a tight tolerance of ±0.5%, ensuring consistent performance in precision circuits. The network operates over a wide temperature range of 70°C to 125°C (derated) with a maximum operating temperature of 125°C, making it suitable for environments requiring thermal stability. Its thin-film technology delivers excellent ±100ppm/°C temperature coefficient, minimizing resistance drift under thermal stress.

GUS-QS8B-01-1870-D Features

• High Power Handling: Total power rating of 0.75W (3/4W) with 0.05W (1/20W) per resistor, ideal for compact designs.
• Robust Construction: Gull-wing termination and QSOP package ensure reliable surface-mount assembly, with dimensions of 4.9mm (L) × 6.02mm (D) × 1.47mm (H) and tight tolerances (±0.1mm height/length, ±0.2mm depth).
• Precision Performance: 0.5% tolerance and ±100ppm/°C TCR for applications requiring stable resistance values.
• High Voltage Rating: Supports up to 100V, suitable for industrial and instrumentation circuits.
• Non-Automotive, Non-PPAP: Optimized for general electronics, though not compliant with EU RoHS.

GUS-QS8B-01-1870-D Applications

This resistor network excels in:

• Analog Signal Processing: Precision dividers, DAC/ADC interfaces, and sensor conditioning circuits.
• Test & Measurement Equipment: Calibration systems and high-accuracy instrumentation.
• Industrial Control Systems: PLCs, motor drives, and power management modules.
• Medical Electronics: Patient monitoring devices where stability and low drift are critical.
  Its compact QSOP footprint and thin-film reliability make it superior to thicker-film networks in space-constrained, high-performance designs.
