GQ8B0256R0DT Description

The GQ8B0256R0DT 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 15 resistors, each with a 56Ω resistance value and a tight 0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. Built on a ceramic substrate, it offers superior thermal stability and reliability across a wide temperature range of -70°C to +125°C. With a ±50ppm/°C temperature coefficient, this network minimizes resistance drift under thermal stress, making it ideal for precision analog and digital systems.

GQ8B0256R0DT Features

• High Power Handling: Delivers 0.75W (3/4W) total power (0.05W per resistor), enabling robust performance in compact designs.
• Low TCR: ±50ppm/°C ensures minimal resistance variation across temperature fluctuations.
• Precision Tolerance: 0.5% tolerance guarantees consistent performance in critical circuits.
• Durable Construction: Ceramic case and gull-wing termination provide mechanical strength and solderability for surface-mount (SMD) applications.
• Space-Efficient: Compact QSOP package (4.9mm x 6.02mm x 1.47mm) with 0.64mm pitch suits high-density PCB layouts.
• High Voltage Rating: Supports up to 100V, suitable for industrial and automotive-grade applications (though not PPAP/automotive-certified).
