GS4A011871FT

GS4A011871FT Description

The GS4A011871FT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and robust thermal performance. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 1.87KΩ resistance and a tight ±1% tolerance. Encased in a rectangular ceramic SOIC package, it offers excellent thermal stability with a ±100ppm/°C temperature coefficient and operates reliably across a wide temperature range of 70°C to 125°C. With a maximum voltage rating of 100V and a power rating of 0.4W (0.1W per resistor), this network is engineered for demanding environments. Its gull-wing termination ensures secure surface-mount (SMD) assembly, while the ceramic construction enhances durability and heat dissipation.
