GQ0A0148R7FDT Description

The GQ0A0148R7FDT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP (Quarter Small Outline Package) device features 10 isolated resistors, each with a 48.7 Ω resistance, 1% tolerance, and a ±100 ppm/°C temperature coefficient. Encased in a ceramic package, it offers excellent thermal stability and durability, with a maximum operating temperature of 125°C. The 1W total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. Its gull-wing termination ensures reliable surface-mount (SMD) assembly, while the 0.64mm terminal pitch accommodates high-density PCB designs.

GQ0A0148R7FDT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistor Network (ISOL): Each of the 10 resistors is electrically isolated, enabling flexible circuit design.
• Ceramic QSOP Package: Enhances thermal performance and mechanical robustness in harsh environments.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, ideal for industrial and automotive-adjacent applications.
• 1% Tolerance & ±100ppm/°C TCR: Ensures consistent performance across temperature variations.
• Compact Dimensions: 8.66mm (L) × 6.02mm (W) × 1.47mm (H) with a low 1.63mm seated height, saving board space.
