GUS-QS0B-03-5621-C Description

The GUS-QS0B-03-5621-C 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 5.62KΩ resistance value and an ultra-tight ±0.25% tolerance, ensuring exceptional accuracy in circuit designs. With a ±25ppm/°C temperature coefficient, it delivers stable performance across a wide temperature range of 70°C to 125°C, making it suitable for environments with thermal fluctuations. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating provide robust electrical performance, while the gull-wing termination ensures reliable solderability in automated PCB assembly.

GUS-QS0B-03-5621-C Features

• Precision Thin Film Technology: Offers low noise and high stability for sensitive analog/digital circuits.
• Compact QSOP Package: Measures 8.66mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm length/height), ideal for space-constrained designs.
• High Power Density: 1W total dissipation (distributed across 19 resistors) outperforms similar networks in power handling.
• Automated Assembly-Friendly: Gull-wing leads and 0.64mm pitch enable seamless SMT placement.
• Broad Operating Range: Functions reliably from -55°C to +125°C, with derated power up to 125°C.
• Non-Automotive/Non-PPAP: Optimized for industrial, medical, and instrumentation applications where PPAP compliance isn’t required.
