GS4B031471FAT

GS4B031471FAT Description

The GS4B031471FAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding circuit applications. This 7-resistor array provides a 1.47KΩ resistance per element with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range (70°C to 125°C). Housed in an 8-pin SOIC ceramic package, it features gull-wing SMD termination for reliable surface-mount assembly. With a 0.4W total power rating (0.05W per resistor) and a 100V maximum voltage rating, this network is engineered for precision signal conditioning, voltage division, and impedance matching in compact PCB designs.
