GUS-QS8A-03-1540-GF Description

The GUS-QS8A-03-1540-GF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP surface-mount device features 8 isolated resistors, each with a 154 Ω resistance value and a tight 2% tolerance. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it operates reliably across a wide temperature range of -70°C to +125°C, making it suitable for demanding environments. The ±25ppm/°C temperature coefficient ensures stable performance under thermal variations, while the 100V maximum voltage rating enhances durability in high-voltage circuits. Packaged in a tube for automated assembly, this RoHS non-compliant component is ideal for industrial and commercial electronics requiring precision and reliability.

GUS-QS8A-03-1540-GF Features

• Thin-Film Technology: Delivers high accuracy, low noise, and excellent stability.
• Isolated Resistors (ISOL): Each of the 8 resistors operates independently, reducing crosstalk.
• Robust Power Handling: 0.75W total power (0.1W per resistor) with derating up to 125°C.
• Precision Tolerance: 2% resistance tolerance and ±25ppm/°C TCR for consistent performance.
• Compact QSOP Package: 4.9mm (L) x 6.02mm (D) x 1.47mm (H) with 0.64mm pitch gull-wing leads for high-density PCB designs.
• Automotive-Grade Alternatives: While not automotive-qualified (PPAP: No), its wide temperature range suits industrial applications.

GUS-QS8A-03-1540-GF Applications

• Signal Conditioning: Precision voltage dividers and feedback networks in op-amp circuits.
• Medical Electronics: Patient monitoring systems requiring stable, low-drift resistors.
