GS4B021242FFT

GS4B021242FFT Description

The GS4B021242FFT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package, designed for precision applications requiring stable thin-film resistance. With a 12.4KΩ resistance value and a tight ±1% absolute tolerance, this ceramic-based network ensures reliable signal conditioning and voltage division. Its ±50ppm/°C temperature coefficient and 125°C maximum operating temperature make it suitable for environments with thermal fluctuations. The SOIC-C series construction offers robust mechanical stability, while the gull-wing termination facilitates easy surface mounting. Rated for 100V maximum voltage and 0.4W total power dissipation, it balances compactness (4.9mm × 5.99mm × 1.45mm) with durability.
