GS4A021242FT

GS4A021242FT Description

The GS4A021242FT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 12.4 kΩ resistance and a tight ±1% tolerance. Its SOIC-C series construction ensures excellent thermal stability, with a low ±50 ppm/°C temperature coefficient, making it ideal for environments with fluctuating temperatures. The network operates within a wide temperature range of 70°C to 125°C and can handle a maximum voltage rating of 100V, with a derated power capability up to 125°C. Encased in a rectangular ceramic package, it offers superior durability and heat dissipation compared to plastic alternatives.
