GUS-QS8B-02-2101-D Description

The GUS-QS8B-02-2101-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 2.1KΩ resistance value and an ultra-tight ±0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±50ppm/°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 (0.05W per resistor) and 100V maximum voltage rating provide robust handling of moderate power loads. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting in space-constrained designs.

GUS-QS8B-02-2101-D Features

• Precision Thin Film Technology: Ensures low noise and high stability for sensitive analog circuits.
• Compact QSOP Package: Measures 4.9mm (L) × 6.02mm (D) × 1.47mm (H), ideal for high-density PCBs.
• High Power Density: 0.75W total dissipation (15 resistors) in a minimal footprint.
• Wide Temperature Range: Derated operation up to 125°C, suitable for industrial and automotive-adjacent applications (though not PPAP/Automotive certified).
• BUS Circuit Designator: Optimized for bus termination and pull-up/pull-down networks.
• Non-RoHS Compliant: May be preferred for legacy or specialized systems requiring leaded components.
