GUS-QS8A-02-2700-BB Description

The GUS-QS8A-02-2700-BB 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 270Ω resistance value with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Housed in a compact 16-pin QSOP (QSOP-16) package, it offers a 0.75W (3/4W) total power rating (0.1W per resistor) and supports a maximum voltage rating of 100V. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting in space-constrained designs.

GUS-QS8A-02-2700-BB Features

• Precision Thin Film Technology: Delivers high accuracy (±0.1%) and low TCR (±50ppm/°C) for critical analog/digital circuits.
• Isolated Circuit Design (ISOL): Each resistor operates independently, ideal for signal isolation or multi-channel applications.
• Robust Power Handling: 0.75W total dissipation (0.1W per resistor) with derating up to 125°C.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), optimizing board space.
• Automated Assembly-Friendly: Gull-wing leads and tube packaging streamline high-volume SMT processes.
• Wide Voltage Range: Supports up to 100V, suitable for industrial and instrumentation systems.
