GQ0A0290R9FCT Description

The GQ0A0290R9FCT 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 integrates 10 isolated resistors, each with a resistance value of 90.9Ω, a tight tolerance of ±1%, and a low temperature coefficient of ±50ppm/°C. Encased in a robust ceramic package, it offers excellent thermal stability and reliability across an operating temperature range of 70°C to 125°C. With a 1W total power rating (0.1W per resistor) and a maximum voltage rating of 100V, this network is ideal for demanding analog and digital circuits requiring consistent performance under varying conditions.

GQ0A0290R9FCT Features

• Precision Thin Film Technology: Delivers high accuracy (±1%) and low TCR (±50ppm/°C), ensuring stable performance in temperature-sensitive applications.
• Isolated Resistor Network (ISOL): Each of the 10 resistors is electrically isolated, providing flexibility in circuit design and reducing crosstalk.
• Ceramic QSOP Package: Enhances thermal management and mechanical durability, suitable for harsh environments.
• Gull Wing Termination: Facilitates reliable surface-mount assembly (SMD) with a 0.64mm terminal pitch, compatible with automated PCB processes.
• Wide Operating Range: Rated for 125°C maximum temperature, making it suitable for industrial and high-reliability applications.
• Non-Automotive (PPAP No): Optimized for commercial and industrial use where automotive certification is not required.
