GS4A034990FFT

GS4A034990FFT Description

The GS4A034990FFT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a resistance value of 499Ω and a tight ±1% absolute tolerance. Its ±25ppm/°C temperature coefficient ensures stable performance across a wide operating temperature range of -70°C to +125°C. The SOIC package (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations offers robust surface-mount compatibility, while the ceramic construction enhances thermal and mechanical reliability. Rated for 0.1W per resistor (0.4W total) and 100V maximum voltage, it is ideal for precision analog and digital circuits.
