GQ0A0290R9GT

GQ0A0290R9GT Description

The GQ0A0290R9GT 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 in demanding circuits. The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) integration, while the ±50 ppm/°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 100V maximum voltage rating, this network is engineered for durability in industrial and telecom environments.

GQ0A0290R9GT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±2% tolerance) for signal conditioning and analog circuits.
• Robust Ceramic Package: Enhances thermal management and mechanical strength, ideal for harsh environments.
• Isolated Resistor Design (ISOL): Each of the 10 resistors operates independently, reducing crosstalk in multi-channel systems.
• High Power Handling: 1W total dissipation (0.1W per resistor) outperforms standard arrays in power-sensitive designs.
• Wide Temperature Range: Stable performance from -70°C to +125°C, suitable for automotive (non-AECQ) and industrial applications.
• QSOP Gull Wing Termination: Facilitates automated PCB assembly with a 0.64mm terminal pitch and compact 8.66mm x 6.02mm footprint.
