GQCA022490GGT

GQCA022490GGT Description

The GQCA022490GGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and tight tolerances. This 24-pin QSOP package integrates 12 isolated resistors, each with a 249Ω resistance value and a 2% tolerance, ensuring consistent performance in demanding circuits. The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) assembly, while the ±50ppm/°C temperature coefficient guarantees minimal resistance drift across the -70°C to +125°C operating range. With a 100V maximum voltage rating and 0.1W power dissipation per resistor (1W total), this network is ideal for analog signal conditioning, isolation, and precision voltage division.

GQCA022490GGT Features

• High Precision: Thin-film technology delivers ±2% tolerance and ±50ppm/°C TCR for stable performance.
• Robust Construction: Ceramic substrate enhances thermal stability and mechanical durability.
• Isolated Design: 12 independent resistors (ISOL circuit designator) prevent crosstalk in sensitive applications.
• Space-Efficient: Compact QSOP package (8.66mm x 6.02mm x 1.47mm) with 0.64mm pitch suits high-density PCBs.
• Wide Operating Range: Rated for -70°C to +125°C, derated up to 125°C for harsh environments.
• Reliable Termination: Gull-wing leads ensure secure soldering and vibration resistance.
