GUS-QS0B-03-1621-D Description

The GUS-QS0B-03-1621-D from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP (Quarter Small Outline Package) device integrates 19 resistors, each with a 1.62KΩ 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. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for high-reliability systems. Its gull-wing termination and surface-mount design facilitate automated assembly, while the tube packaging ensures safe handling and storage.

GUS-QS0B-03-1621-D Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog circuits.
• Compact QSOP Package: Measures 8.66mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm length/height, ±0.2mm depth).
• High Power Density: 1W total dissipation (distributed across 19 resistors) in a minimal footprint.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power handling.
• Automation-Friendly: 0.64mm terminal pitch and gull-wing leads optimize pick-and-place efficiency.
• Non-Automotive/Non-PPAP: Ideal for industrial, medical, and instrumentation applications where PPAP compliance is not required.
