GS4B014302FAT

GS4B014302FAT Description

The GS4B014302FAT from TT Electronics/IRC is a high-performance 7-resistor thin-film network designed for precision applications. Encased in a ceramic SOIC-8 package, it offers a 43KΩ resistance per resistor with a tight 1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a -70°C to +125°C operating range. With a 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating, this surface-mount network is ideal for space-constrained designs requiring reliability under thermal stress. Its gull-wing termination and 1.27mm terminal pitch facilitate easy PCB integration, while the ceramic substrate enhances thermal dissipation and durability.
