GUS-QS0B-03-1621-DC Description

The GUS-QS0B-03-1621-DC from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP package integrates 19 resistors, each with a 1.62KΩ resistance value and a 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 70°C to 125°C derated power range, making it suitable for environments with fluctuating thermal conditions. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating provide robust electrical performance in compact designs.

GUS-QS0B-03-1621-DC Features

• Precision Thin Film Technology: Ensures low noise, high stability, and minimal drift over time.
• Compact QSOP Package: Measures 8.66mm (L) × 6.02mm (D) × 1.47mm (H), ideal for space-constrained PCBs.
• Gull Wing Termination: Facilitates reliable surface-mount (SMD) assembly with a 0.64mm terminal pitch.
• Wide Temperature Range: Operates reliably up to 125°C, suitable for industrial and automotive-adjacent applications (though not PPAP/Automotive certified).
• High Power Density: 1W total dissipation across the network, enabling efficient heat management.
• Non-RoHS Compliance: May be preferred for legacy or specialized systems requiring leaded components.
