GQCA032491JFT Description

The GQCA032491JFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and thermal performance. This 24-pin QSOP package features 12 isolated resistors, each with a 2.49KΩ resistance, 5% tolerance, and a ±25ppm/°C temperature coefficient, ensuring reliable operation across a 70°C to 125°C derated power range. The ceramic case style and gull-wing termination provide excellent mechanical durability and ease of surface-mount (SMD) assembly. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network is ideal for demanding analog and digital circuits.

GQCA032491JFT Features

• High Precision: Thin-film technology ensures low TCR (±25ppm/°C) and tight tolerance (±5%).
• Robust Construction: Ceramic substrate enhances thermal stability and mechanical strength.
• Compact Design: 8.66mm × 6.02mm × 1.47mm footprint with 0.64mm terminal pitch for high-density PCB layouts.
• Isolated Configuration: 12 independent resistors (ISOL circuit designator) prevent crosstalk in multi-channel systems.
• Wide Operating Range: Rated for -55°C to +125°C, suitable for industrial and telecom environments.
• Non-Automotive: Not PPAP-capable, optimized for general-purpose and professional electronics.
