GQCA031402JFT Description

The GQCA031402JFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. This 24-pin QSOP package features 12 isolated resistors, each with a 14KΩ resistance (5% tolerance) and a ±25ppm/°C temperature coefficient, ensuring minimal drift across its operating range of -70°C to +125°C. Encased in a ceramic substrate, the network delivers 0.1W power dissipation per resistor (1W total) and supports 100V maximum voltage ratings, making it suitable for high-reliability circuits. Its gull-wing termination and 0.64mm pitch enable seamless surface-mount (SMD) integration in space-constrained designs.

GQCA031402JFT Features

• Precision Thin Film Technology: Offers superior stability and low noise compared to thick-film alternatives.
• Isolated Resistor Configuration (ISOL): Each of the 12 resistors operates independently, ideal for signal isolation or multi-channel applications.
• Wide Temperature Range: Derated power operation up to 125°C ensures reliability in harsh environments.
• Compact QSOP Package: 8.66mm × 6.02mm × 1.47mm dimensions with tight tolerances (±0.1mm length/height) for high-density PCB layouts.
• Robust Ceramic Construction: Enhances thermal dissipation and mechanical durability.
• Non-Automotive (PPAP No): Optimized for industrial, telecom, and instrumentation use.

GQCA031402JFT Applications
