GUS-QS0B-03-8250-DA Description

The GUS-QS0B-03-8250-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 825Ω 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 range of -55°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 and 0.64mm terminal pitch facilitate reliable PCB mounting in space-constrained designs.

GUS-QS0B-03-8250-DA Features

• Precision Thin Film Technology: Ensures 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) outperforms similar networks in power handling.
• Automotive-Grade Alternatives: While not PPAP or automotive-certified, its 125°C maximum operating temperature suits industrial and telecom applications.
• Non-RoHS Compliant: Ideal for legacy systems or niche applications requiring leaded components.
• BUS Circuit Designator: Optimized for bus termination, voltage reference, and differential signal applications.
