GUS-QS8A-03-1331-CA Description

The GUS-QS8A-03-1331-CA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 8 isolated resistors, each with a 1.33KΩ 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 -70°C to +125°C, making it suitable for environments with thermal fluctuations. The 0.75W (3/4W) total power rating and 100V maximum voltage rating provide robust handling of moderate power loads while maintaining reliability.

GUS-QS8A-03-1331-CA Features

• Precision Thin Film Technology: Ensures low noise, high stability, and minimal drift over time.
• Isolated Resistor Configuration (ISOL): Each of the 8 resistors operates independently, ideal for multi-channel isolation.
• Compact QSOP Package: Measures just 4.9mm (L) x 6.02mm (D) x 1.47mm (H), saving PCB space in dense layouts.
• Gull Wing Termination: Facilitates reliable soldering and inspection in automated SMT processes.
• Derated Power Handling: Maintains performance up to 125°C with derated power at elevated temperatures.
• Non-Automotive, Non-PPAP: Optimized for industrial, medical, and instrumentation applications where PPAP compliance is not required.
