GS8A028451CBT Description

The GS8A028451CBT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding isolation and signal conditioning applications. Encased in a ceramic SOIC-16 package, it offers an 8.45KΩ resistance per element with an ultra-tight ±0.25% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The 0.1W power rating per resistor (0.8W total) and 100V maximum voltage rating make it suitable for precision analog circuits. Its gull-wing termination and surface-mount design (9.91mm x 5.99mm x 1.45mm) facilitate compact PCB layouts.

GS8A028451CBT Features

• Isolation-Centric Design: Labeled "ISOL", it’s optimized for galvanic isolation in mixed-signal systems.
• Ceramic Construction: Enhances thermal performance and durability vs. plastic alternatives.
• Thin Film Technology: Delivers superior accuracy (±0.25%) and low TCR (±50ppm/°C).
• High-Density Integration: 8 resistors in a 16-pin SOIC, saving board space.
• Robust Power Handling: 0.8W total dissipation at 125°C with derating.
