GUS-QS8A-03-2551-FF Description

The GUS-QS8A-03-2551-FF from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. With a 2.55KΩ resistance value and a tight 1% tolerance, this component ensures reliable signal conditioning and voltage division in compact circuits. Housed in a 16-pin QSOP package, it features gull-wing SMD termination for secure surface mounting. The device operates over a wide temperature range of 70°C to 125°C (derated) and withstands up to 125°C maximum, making it suitable for demanding environments. Its ±25ppm/°C temperature coefficient guarantees stability under thermal stress, while the 0.75W (3/4W) total power rating (0.1W per resistor) balances efficiency and durability.

GUS-QS8A-03-2551-FF Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±1%) for sensitive analog/digital circuits.
• Isolated Resistor Network (ISOL): Each of the 8 resistors is electrically isolated, enabling flexible circuit design.
• Robust Construction: QSOP package (4.9mm x 6.02mm x 1.47mm) with a 0.64mm terminal pitch ensures space efficiency and mechanical resilience.
• High Voltage Handling: Supports up to 100V maximum voltage, ideal for industrial and instrumentation applications.
• Stable Performance: ±25ppm/°C TCR minimizes resistance drift across temperature fluctuations.
• Tube Packaging: Facilitates automated assembly processes, reducing handling errors.
