GUS-QS8A-02-1821-CA Description

The GUS-QS8A-02-1821-CA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 8-resistor isolated network features a 1.82KΩ resistance value with an ultra-tight ±0.25% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of -70°C to +125°C. Housed in a compact 16-pin QSOP package with gull-wing terminations, it offers a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for high-density PCB designs. The isolated (ISOL) circuit design provides individual resistor independence, enhancing flexibility in circuit configurations.

GUS-QS8A-02-1821-CA Features

• Precision Thin Film Technology: Delivers superior accuracy (±0.25%) and low TCR (±50ppm/°C) for stable operation in thermal-variable environments.
• High Power Density: 0.75W total power rating in a miniature 4.9mm x 6.02mm x 1.47mm QSOP package, ideal for space-constrained applications.
• Isolated Resistor Network: Eight independent 1.82KΩ resistors enable versatile circuit designs without cross-talk.
• Robust Construction: Gull-wing SMD termination ensures reliable solder joints, while the tube packaging protects components during handling.
• Wide Operating Range: Rated for -70°C to +125°C, suitable for industrial and automotive-grade environments (though non-PPAP and non-automotive certified).
