GUS-QS0B-03-5901-CA Description

The GUS-QS0B-03-5901-CA 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 5.9K Ohm resistance and an ultra-tight 0.25% 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 range of -55°C to +125°C, making it suitable for environments with fluctuating thermal conditions. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating further enhance its reliability in high-density PCB designs.

GUS-QS0B-03-5901-CA Features

• Precision Thin Film Technology: Offers low noise and high stability for critical analog circuits.
• Compact QSOP Package: 8.66mm (L) × 6.02mm (W) × 1.47mm (H) footprint saves board space while providing 20 gull-wing terminals for robust SMD mounting.
• High Power Handling: 1W total dissipation (distributed across 19 resistors) outperforms similar networks in power density.
• Automotive-Grade Alternatives: While not automotive-qualified (PPAP: No), its 125°C max operating temperature suits industrial and telecom applications.
