GQ8A0254R9JDT Description

The GQ8A0254R9JDT from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications requiring stable resistance values and thermal reliability. Encased in a ceramic QSOP package, this 16-pin surface-mount device (SMD) offers a 54.9 Ohm resistance per resistor with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring consistent performance across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, it is engineered for demanding circuits, particularly in isolated (ISOL) configurations. The gull-wing termination facilitates reliable PCB mounting, while the ceramic construction enhances durability and heat dissipation.

GQ8A0254R9JDT Features

• Thin Film Technology: Delivers superior accuracy and low noise compared to thick-film alternatives.
• High Power Handling: 0.1W per resistor (0.75W total) enables use in power-sensitive designs.
• Stable Thermal Performance: ±50ppm/°C TCR minimizes resistance drift under thermal stress.
• Robust Packaging: Ceramic QSOP case ensures mechanical strength and thermal conductivity.
• Precision Dimensions: Tight tolerances (±0.1mm height/length, ±0.2mm depth) for consistent PCB fit.
• Isolated Circuit Design: Ideal for applications requiring electrical separation between channels.
