GS4A0254R9GDT Description

The GS4A0254R9GDT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. Housed in an 8-pin narrow SOIC package, it features four isolated thin-film resistors, each with a resistance value of 54.9Ω and a tight ±2% absolute tolerance. The device operates over a wide temperature range of -70°C to +125°C, with a derated power capability up to 125°C, ensuring reliability in demanding environments. Its ±50ppm/°C temperature coefficient guarantees stable performance under thermal variations. The SOIC-C series construction offers superior mechanical robustness, with a compact footprint (4.9mm × 5.99mm × 1.45mm) and gull-wing termination for easy surface-mount assembly.
