GQCA013570JFT

GQCA013570JFT Description

The GQCA013570JFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 24-pin QSOP package features 12 isolated resistors, each with a 357 Ω resistance value and a 5% tolerance, ensuring reliable performance in demanding circuits. The ceramic case style and gull-wing termination enable robust surface-mount (SMD) integration, while the thin-film technology delivers excellent stability with a ±100 ppm/°C temperature coefficient. Rated for 1W total power dissipation (0.1W per resistor) and 100V maximum voltage, it operates across a wide temperature range of 70°C to 125°C, making it suitable for industrial and telecom environments. Packaged in a tube, this non-automotive, non-PPAP component is ideal for prototyping and low-to-medium volume production.

GQCA013570JFT Features

• High Precision: 5% tolerance and ±100 ppm/°C TCR ensure stable performance under thermal stress.
• Robust Construction: Ceramic substrate and QSOP package enhance durability and heat dissipation.
• Isolated Design: 12 independent resistors (ISOL circuit designator) prevent cross-talk in sensitive applications.
• Space-Efficient: Compact 8.66mm × 6.02mm × 1.47mm dimensions with 0.64mm terminal pitch suit high-density PCBs.
• Wide Operating Range: 125°C maximum temperature and 100V rating support harsh environments.
• Thin-Film Advantage: Superior accuracy and lower noise compared to thick-film alternatives.
