GS4A027872BBT Description

The GS4A027872BBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC package, it features four isolated thin-film resistors, each with a resistance value of 78.7KΩ and an absolute tolerance of ±0.1%. The device operates over a wide temperature range of -70°C to +125°C, with a derated power range up to 125°C, ensuring reliability in harsh environments. Its ±50ppm/°C temperature coefficient and 0.1% ratio tolerance make it ideal for precision analog circuits. The SOIC-C series construction offers excellent stability, with a 0.4W total power rating (0.1W per resistor) and a maximum voltage rating of 100V.
