GS8A012490DT Description

The GS8A012490DT 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 249Ω resistance per element with an ultra-tight ±0.5% tolerance and ±100ppm/°C temperature coefficient, this ceramic-based thin-film network ensures stable performance across a -70°C to +125°C operating range. Its 100V maximum voltage rating and 0.1W power dissipation per resistor (0.8W total) make it suitable for precision analog and digital circuits. The gull-wing termination and 1.27mm pitch facilitate reliable PCB assembly, while the 9.91mm × 5.99mm × 1.45mm compact footprint optimizes space efficiency.
