GUS-QS8B-03-6191-D Description

The GUS-QS8B-03-6191-D from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP device integrates 15 resistors, each with a 6.19KΩ 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 -70°C to +125°C, making it suitable for environments with thermal fluctuations. The 0.75W (3/4W) total power rating (0.05W per resistor) and 100V maximum voltage rating provide robust handling of moderate power loads while maintaining reliability.

GUS-QS8B-03-6191-D Features

• Precision Thin Film Technology: Ensures low noise, high stability, and minimal drift over time.
• Compact QSOP Package: Measures 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with ±0.1mm length/height tolerances, ideal for space-constrained PCB designs.
• Gull Wing Termination: Facilitates reliable surface-mount (SMD) soldering with a 0.64mm terminal pitch for automated assembly.
• Derated Power Handling: Operates at full performance up to 125°C, with derating applied beyond 70°C.
• Non-Automotive, Non-PPAP: Optimized for industrial and commercial applications where PPAP compliance is not required.
• Non-RoHS Compliant: Suitable for legacy or exempted applications requiring leaded components.
