GQ0A0228R7GCT Description

The GQ0A0228R7GCT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP package features 10 isolated resistors, each with a 28.7 Ω resistance, 2% tolerance, and a ±50 ppm/°C temperature coefficient. Encased in a ceramic substrate, it offers superior thermal stability and durability. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, it operates reliably across a wide temperature range of 70°C to 125°C. The gull-wing termination ensures secure surface-mount (SMD) assembly, while the 0.64mm terminal pitch facilitates high-density PCB layouts.

GQ0A0228R7GCT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive circuits.
• Isolated Resistor Network (ISOL): Each of the 10 resistors is electrically isolated, enabling flexible circuit design.
• Ceramic Case: Enhances thermal dissipation and mechanical robustness.
• High Power Handling: 1W total (0.1W per resistor) with derating up to 125°C.
• Compact QSOP Package: 8.66mm × 6.02mm × 1.47mm dimensions, ideal for space-constrained applications.
• Gull-Wing SMD Termination: Ensures reliable solder joints and compatibility with automated assembly.
