GUS-QS8A-02-5230-CB Description

The GUS-QS8A-02-5230-CB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP-packaged device integrates 8 isolated resistors, each with a 523Ω resistance and an ultra-tight ±0.25% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±50ppm/°C temperature coefficient, it delivers stable performance across a wide temperature range of 70°C to 125°C (derated) and up to 125°C maximum operating temperature. The network supports a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for precision analog and mixed-signal designs.

GUS-QS8A-02-5230-CB Features

• High Precision: Thin-film technology with ±0.25% tolerance and ±50ppm/°C TCR for minimal drift.
• Robust Construction: QSOP package (4.9mm x 6.02mm x 1.47mm) with gull-wing terminals (0.64mm pitch) for reliable SMT assembly.
• Isolated Resistors: Eight 523Ω resistors with independent circuits (ISOL designator), ideal for multi-channel isolation.
• Power Efficiency: 0.75W total dissipation (0.1W per resistor) balances compact size with thermal performance.
