GS8A0140R2DDT

GS8A0140R2DDT Description

The GS8A0140R2DDT from TT Electronics/IRC is a high-precision 8-resistor network designed for demanding isolation applications. Housed in a 16-pin narrow SOIC ceramic package, it features isolated thin-film resistors with a resistance value of 40.2Ω and an absolute tolerance of ±0.5%. The device operates over a wide temperature range (-70°C to +125°C) with a ±100ppm/°C temperature coefficient, ensuring stability in harsh environments. Its 0.1W power rating per resistor (0.8W total) and 100V maximum voltage rating make it suitable for precision analog and digital circuits. The gull-wing termination and surface-mount design facilitate automated assembly, while the ceramic case enhances thermal and mechanical reliability.
