GQ0A0290R9GGT Description

The GQ0A0290R9GGT 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 90.9 Ω resistance value and a tight 2% tolerance, ensuring consistent performance. The ceramic case style and gull-wing termination make it ideal for surface-mount (SMD) applications, while its ±50ppm/°C temperature coefficient guarantees stability across a wide operating range of 70°C to 125°C. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is engineered for reliability in demanding circuits.

GQ0A0290R9GGT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±2% tolerance).
• Isolated Resistor Design (ISOL): Each of the 10 resistors operates independently, reducing crosstalk.
• Robust Ceramic Package: Enhances thermal performance and durability in harsh environments.
• Wide Temperature Range: Stable operation from 70°C to 125°C with derated power.
• Compact QSOP Form Factor: 8.66mm x 6.02mm x 1.47mm dimensions with 0.64mm pitch, saving PCB space.
• Gull Wing Termination: Ensures reliable solder joints for automated assembly processes.
