GQCA0249R9JGT Description

The GQCA0249R9JGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low temperature coefficients. This 24-pin QSOP package integrates 12 isolated resistors, each with a 49.9Ω resistance and a 5% tolerance, delivering a total power rating of 1W (0.1W per resistor). The ceramic case ensures excellent thermal stability, with an operating temperature range of 70°C to 125°C and a maximum voltage rating of 100V. Its gull-wing termination and surface-mount design make it ideal for automated assembly processes.

GQCA0249R9JGT Features

• Thin-film technology for superior stability and low noise (±50ppm/°C TCR).
• Isolated circuit design (ISOL) for independent resistor performance.
• Compact QSOP package (8.66mm × 6.02mm × 1.47mm) with tight tolerances (±0.1mm length/height).
• High power density (1W total, 0.1W per resistor) in a small footprint.
• Wide temperature range (-55°C to +125°C) with derated power up to 125°C.
• Non-automotive, non-PPAP compliant, suited for industrial and commercial applications.
