GS8A0247R5FT

GS8A0247R5FT Description

The GS8A0247R5FT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation applications. This 8-resistor array features a 47.5Ω resistance per element with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a 16-pin SOIC ceramic package, it offers 0.1W power dissipation per resistor (0.8W total) and a 100V maximum voltage rating, making it suitable for high-reliability circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its isolated (ISOL) circuit configuration enhances signal integrity in noise-sensitive environments.
