GUS-QS0B-03-2741-DA Description

The GUS-QS0B-03-2741-DA 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 2.74KΩ 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 wide operating 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 handling of moderate power loads. Its gull-wing termination ensures reliable solder joints in automated PCB assembly.

GUS-QS0B-03-2741-DA 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), ideal for space-constrained designs.
• High Power Density: 1W total dissipation (distributed across 19 resistors) outperforms similar networks in power handling.
• Extended Temperature Range: Operates reliably up to 125°C, suited for industrial and automotive-adjacent applications (though not PPAP/automotive-certified).
• BUS Circuit Designator: Optimized for bus termination and pull-up/pull-down networks in digital systems.
• Non-RoHS Compliant: Suitable for legacy or exempted applications requiring leaded components.
