GS4A021472BT

GS4A021472BT Description

The GS4A021472BT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC package, it features four isolated thin-film resistors, each with a 14.7 kΩ resistance and an ultra-tight ±0.1% tolerance. The device operates over a wide temperature range of 70°C to 125°C with a ±50 ppm/°C temperature coefficient, ensuring stability in fluctuating environments. Its 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating make it suitable for precision analog and digital circuits. The SOIC-C series construction offers low crosstalk due to isolated elements, while the gull-wing termination ensures reliable surface-mount assembly.
