GS4A026040BBT Description

The GS4A026040BBT by TT Electronics/IRC is a high-precision 4-resistor isolated network in an 8-pin narrow SOIC (SOIC-C) ceramic package, designed for demanding circuit isolation applications. Featuring 604Ω resistance per element with an exceptional ±0.1% absolute tolerance and ±0.1% ratio tolerance, this thin-film resistor network ensures minimal deviation in matched resistance values. Its ±50ppm/°C temperature coefficient and 125°C maximum operating temperature guarantee stable performance across industrial environments. The 100V maximum voltage rating and 0.1W power rating per resistor (0.4W total) make it suitable for precision analog and signal conditioning circuits. Encased in a rectangular ceramic SOIC package (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations, it offers robust mechanical stability and ease of surface-mount assembly.
