GS4A021542FFT

GS4A021542FFT Description

The GS4A021542FFT 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 15.4 kΩ resistance and a tight ±1% absolute tolerance. Its ±50 ppm/°C temperature coefficient ensures stable performance across a wide operating temperature range of -70°C to +125°C. The SOIC package (4.9 mm × 5.99 mm × 1.45 mm) with gull-wing terminations is optimized for surface-mount assembly, offering robust mechanical and thermal reliability. With a 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating, this network is ideal for precision analog and digital circuits.
