GS8A0127R4DCT Description

The GS8A0127R4DCT 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 27.4Ω resistance per element with an ultra-tight ±0.5% absolute tolerance and ±0.25% ratio tolerance, this ceramic-based thin-film network ensures exceptional stability and accuracy. Its ±100ppm/°C temperature coefficient and 125°C maximum operating temperature make it suitable for environments requiring reliable performance under thermal stress. The SOIC-C series construction offers robust 100V maximum voltage rating and 0.1W power dissipation per resistor, with a compact footprint (9.91mm × 5.99mm × 1.45mm) ideal for space-constrained designs.
