GS4B021581FT

GS4B021581FT Description

The GS4B021581FT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package. Designed for precision applications, it features a 1.58KΩ resistance value with a tight ±1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a -70°C to +125°C operating range. The ceramic thin-film construction delivers superior reliability, while the 0.05W (1/20) power rating per resistor and 0.4W total power rating make it suitable for low-power circuits. Its 100V maximum voltage rating and surface-mount gull-wing termination enable robust integration into compact PCB designs.
