GUS-QS0B-02-1021-DB Description

The GUS-QS0B-02-1021-DB is a high-precision thin-film resistor network from TT Electronics/IRC, designed for applications requiring tight tolerance and stable performance. This 20-pin QSOP surface-mount device integrates 19 resistors, each with a 1.02KΩ resistance value and an exceptional ±0.5% tolerance. The network operates over a wide temperature range of 70°C to 125°C, with a ±50ppm/°C temperature coefficient, ensuring minimal resistance drift under varying thermal conditions. Its 1W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. Packaged in a tube, this non-automotive, non-PPAP compliant component is ideal for precision electronics.

GUS-QS0B-02-1021-DB Features

• Thin Film Technology: Delivers superior stability, low noise, and high accuracy compared to thick-film alternatives.
• Compact QSOP Package: Measures 8.66mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm L/H, ±0.2mm D), saving PCB space.
• Gull Wing Termination: Ensures reliable surface-mount (SMD) soldering with a 0.64mm terminal pitch.
• High Power Density: 1W total dissipation (distributed across 19 resistors) supports power-sensitive designs.
• Wide Operating Range: Functions reliably from -55°C to 125°C, with derated power up to 125°C.
• Precision Tolerance: ±0.5% resistance tolerance and ±50ppm/°C TCR enhance signal integrity in critical applications.
