GS8A0227R4JFT Description

The GS8A0227R4JFT from TT Electronics/IRC is a high-performance 8-resistor isolated network designed for precision applications. Encased in a ceramic SOIC-16 package, it features 27.4Ω thin-film resistors with a ±5% tolerance and ±50ppm/°C temperature coefficient, ensuring stable performance across a -70°C to +125°C operating range. With a 0.1W power rating per resistor (0.8W total) and 100V maximum voltage rating, this surface-mount device (SMD) is ideal for demanding environments. Its gull-wing termination and 1.27mm pitch facilitate reliable PCB integration, while the ceramic substrate enhances thermal and mechanical robustness.

GS8A0227R4JFT Features

• Isolated Circuit Design (ISOL): Each resistor operates independently, eliminating crosstalk.
• High Power Density: 0.8W total dissipation in a compact 9.91×5.99×1.45mm footprint.
• Stable Thin-Film Technology: Delivers low noise and superior accuracy vs. thick-film alternatives.
• Wide Temperature Range: Derated power operation up to 125°C, suitable for industrial and automotive (non-AECQ) applications.
• Mechanical Durability: Ceramic case resists vibration and thermal shock, outperforming plastic-encased networks.
• Precision Gull-Wing Leads: Ensures reliable solder joints in automated assembly processes.
