GUS-QS8A-02-6340-JF Description

The GUS-QS8A-02-6340-JF 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 634Ω resistance value and a 5% tolerance. With a power rating of 0.75W (3/4W) total and 0.1W (1/10W) per resistor, it operates reliably within a temperature range of 70°C to 125°C (derated) and can withstand up to 125°C at full load. The ±50ppm/°C temperature coefficient ensures stable performance under thermal variations, while the 100V maximum voltage rating makes it suitable for medium-voltage circuits. Packaged in a tube for secure handling, this non-automotive, non-PPAP compliant component is ideal for industrial and commercial electronics.

GUS-QS8A-02-6340-JF Features

• Thin-Film Technology: Delivers high precision and low noise for signal conditioning.
• Isolated Resistors (ISOL): 8 independent resistors in a compact QSOP-16 package (4.9mm x 6.02mm x 1.47mm).
• Robust Power Handling: 0.75W total dissipation with 0.1W per resistor, supporting sustained operation.
• Wide Temperature Range: Stable performance from -55°C to +125°C (non-derated).
• Gull Wing Termination: Ensures reliable surface-mount (SMD) soldering with a 0.64mm pitch.
• Low TCR (±50ppm/°C): Minimizes resistance drift in varying thermal environments.
• Non-Automotive: Optimized for industrial, telecom, and instrumentation applications.

GUS-QS8A-02-6340-JF Applications
