GS8A028451FT Description

The GS8A028451FT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for isolation (ISOL) applications. Encased in a ceramic SOIC-16 package, it offers an 8.45KΩ resistance per resistor with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a -70°C to +125°C operating range. With a 0.8W total power rating (0.1W per resistor) and 100V maximum voltage rating, this surface-mount device (SMD) is engineered for reliability in demanding circuits. Its gull-wing termination and 1.27mm pitch facilitate easy PCB integration, while the ceramic substrate enhances thermal and mechanical durability.

GS8A028451FT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistor Network: Each of the 8 resistors is electrically isolated, ideal for signal separation.
• Robust Ceramic Package: Superior heat dissipation and mechanical strength vs. plastic alternatives.
• Wide Temperature Range: Operates reliably from -70°C to +125°C (derated power above 70°C).
• Surface-Mount Design: 16-pin SOIC with gull-wing leads for automated assembly compatibility.
• Low TCR (±50ppm/°C): Minimizes resistance drift under thermal stress.
