GUS-QS0B-03-2202-D Description

The GUS-QS0B-03-2202-D 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 22KΩ resistance value and a tight 0.5% tolerance, ensuring exceptional accuracy in circuit designs. With a ±25ppm/°C temperature coefficient, it delivers stable performance across a wide operating range of 70°C to 125°C, making it suitable for environments with thermal fluctuations. The network supports a maximum voltage rating of 100V and offers a total power rating of 1W (0.05W per resistor), balancing compactness with robust power handling. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting in space-constrained designs.

GUS-QS0B-03-2202-D Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Compact QSOP Package: Measures 8.66mm (L) × 6.02mm (D) × 1.47mm (H), ideal for high-density PCBs.
• High Power Density: 1W total dissipation (distributed across 19 resistors) in a minimal footprint.
• Automotive-Grade Alternatives: While this model is not PPAP or automotive-qualified, its 125°C max operating temperature suits industrial and telecom applications.
• Non-RoHS Compliance: Note: Not compliant with EU RoHS directives, limiting use in regulated eco-sensitive markets.
