GQCA028251JGT Description

The GQCA028251JGT 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 (Quarter Small Outline Package) device integrates 12 isolated resistors, each rated at 8.25KΩ ±5% tolerance, with a ±50ppm/°C temperature coefficient for minimal drift. Encased in a ceramic package, it offers superior thermal stability and mechanical robustness, making it suitable for demanding environments. The 1W total power rating (0.1W per resistor) and 100V maximum voltage rating ensure reliable operation in circuits requiring moderate power handling.

GQCA028251JGT Features

• High-Density Integration: 12 resistors in a compact 8.66mm × 6.02mm × 1.47mm QSOP package, ideal for space-constrained designs.
• Precision Thin-Film Technology: Delivers low noise and high accuracy (±5% tolerance) with excellent long-term stability.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, ensuring performance in elevated temperatures.
• Isolated Circuit Design (ISOL): Each resistor is electrically isolated, providing flexibility in circuit design.
• Gull Wing Termination: Facilitates reliable surface-mount (SMD) assembly with a 0.64mm terminal pitch for automated PCB placement.
• Ceramic Case: Enhances thermal dissipation and durability compared to plastic-bodied alternatives.
