GUS-QS8A-03-1621-CB Description

The GUS-QS8A-03-1621-CB 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 1.62KΩ 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 thermal fluctuations. The 0.75W (3/4W) total power rating and 100V maximum voltage support robust operation in compact designs.

GUS-QS8A-03-1621-CB Features

• Precision Thin Film Technology: Delivers low noise and high stability for critical analog circuits.
• Isolated Resistor Configuration (ISOL): Each of the 8 resistors operates independently, ideal for multi-channel isolation.
• High Power Handling: 0.1W per resistor (0.75W total) outperforms standard networks in power density.
• Gull Wing Termination: Ensures reliable surface-mount (SMD) soldering with a 0.64mm pitch for high-density PCB layouts.
• Extended Temperature Range: Operates reliably from -55°C to +125°C, with derated power up to 125°C.
• Compact Footprint: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) fits space-constrained applications.
