GS8A0149R9DCT Description

The GS8A0149R9DCT from TT Electronics/IRC is a high-precision 8-resistor isolated network in a 16-pin narrow SOIC package, designed for demanding surface-mount applications. Featuring 49.9Ω thin-film resistors with an absolute tolerance of ±0.5% and ratio tolerance of ±0.25%, this ceramic-based network ensures stable performance across a -70°C to +125°C temperature range. Its ±100ppm/°C temperature coefficient and 100V maximum voltage rating make it suitable for precision analog and digital circuits. The 0.1W power rating per resistor (0.8W total) and gull-wing termination enable reliable operation in compact PCB layouts.
