GQ0A0251R1FDT Description

The GQ0A0251R1FDT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP package features 10 isolated resistors, each with a 51.1Ω resistance, 1% tolerance, and a ±50ppm/°C temperature coefficient. Encased in a ceramic substrate, it offers superior 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 layouts.

GQ0A0251R1FDT 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 operates independently, eliminating crosstalk.
• Ceramic Case Style: Enhances thermal dissipation 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.
• Compact QSOP Package: 8.66mm x 6.02mm footprint and 1.47mm profile save board space without sacrificing performance.
• Non-Automotive (PPAP No): Optimized for general industrial, telecom, and instrumentation use.
