GQ8A024222JT

GQ8A024222JT Description

The GQ8A024222JT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 42.2K Ohm resistance per element with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a 16-pin QSOP ceramic package, it offers a 0.75W (3/4W) total power rating and 0.1W per resistor, making it suitable for demanding circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its 100V maximum voltage rating enhances reliability in high-voltage environments.

GQ8A024222JT Features

• Isolated Circuit Design (ISOL): Ensures independent resistor performance, critical for signal isolation.
• Ceramic Case Style: Provides superior thermal stability and durability compared to plastic alternatives.
• Thin-Film Technology: Delivers low noise and high precision, ideal for analog and mixed-signal circuits.
• Compact Dimensions (4.9mm x 6.02mm x 1.47mm): Saves board space in dense layouts.
• Wide Operating Range (-55°C to +125°C): Suitable for industrial and automotive-grade applications (though not PPAP/automotive-certified).
• Gull-Wing Termination: Improves solder joint reliability under thermal stress.

GQ8A024222JT Applications

This resistor network excels in:

1. Precision Voltage Dividers: Due to its tight tolerance and low TCR, it’s ideal for sensor interfaces and ADC circuits.
