GQ8A028250BBT Description

The GQ8A028250BBT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding isolation and signal conditioning applications. Housed in a 16-pin QSOP ceramic package, it features a 825Ω resistance value per resistor with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -70°C to +125°C. The isolated (ISOL) circuit design provides independent resistors, making it ideal for applications requiring electrical separation. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network delivers reliable performance in compact, surface-mount designs.

GQ8A028250BBT Features

• Precision Thin Film Technology: Ensures low noise, high accuracy, and long-term stability.
• Ceramic QSOP Package: Offers superior thermal performance and mechanical robustness compared to plastic alternatives.
• Gull Wing Termination: Facilitates reliable surface-mount (SMD) assembly with a 0.64mm terminal pitch for high-density PCB layouts.
• Isolated Resistors: Each of the 8 resistors is electrically independent, enabling flexible circuit design.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, with derated power up to 125°C.
• Strict Tolerances: ±0.1mm length/height tolerances and ±0.2mm depth tolerance ensure consistent mechanical fit.
