GQ0A011021GGT Description

The GQ0A011021GGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low thermal drift. This 10-resistor array features a 1.02KΩ resistance per element with a tight 2% tolerance and a ±100ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range of 70°C to 125°C. Housed in a 20-pin QSOP ceramic package, it offers excellent thermal stability and durability, making it suitable for demanding environments. The isolated (ISOL) circuit design allows for independent resistor operation, while the gull-wing termination enables secure surface-mount (SMD) assembly. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is ideal for precision analog and digital circuits.

GQ0A011021GGT Features

• High Precision: 2% tolerance and ±100ppm/°C TCR ensure minimal resistance drift.
• Robust Construction: Ceramic case and thin-film technology provide superior thermal and mechanical stability.
• Space-Efficient: Compact QSOP package (8.66mm x 6.02mm x 1.47mm) with 0.64mm terminal pitch suits high-density PCB designs.
• Isolated Design: 10 independent resistors allow flexible circuit configurations.
• Reliable Termination: Gull-wing leads ensure strong solder joints for surface-mount applications.
• Wide Operating Range: Rated for -55°C to +125°C, with derated power up to 125°C.

GQ0A011021GGT Applications
