GUS-QS8B-03-4121-D Description

The GUS-QS8B-03-4121-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 4.12KΩ resistance value and an ultra-tight 0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±25ppm/°C temperature coefficient, it delivers stable performance across a wide operating temperature range of 70°C to 125°C, making it suitable for environments with thermal fluctuations. The 0.75W (3/4W) total power rating and 100V maximum voltage rating provide robust handling of moderate power loads, while the gull-wing termination ensures reliable solder joints in automated assembly processes.

GUS-QS8B-03-4121-D Features

• Precision Thin Film Technology: Offers low noise and high stability for critical analog circuits.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth), ideal for space-constrained PCBs.
• High Power Density: 0.05W per resistor (15 resistors) enables efficient heat dissipation in dense layouts.
• Automotive-Grade Alternatives: While not PPAP or Automotive qualified, its 125°C maximum operating temperature suits industrial and telecom applications.
• Non-RoHS Compliance: Suitable for legacy systems requiring leaded components.
