GS4B035902FDT Description

The GS4B035902FDT from TT Electronics/IRC is a high-precision 7-resistor thin film network designed for bus applications, housed in an 8-pin SOIC ceramic package. With a 59K Ohm resistance value and tight 1% tolerance, it ensures reliable signal integrity in demanding circuits. The device operates across a wide temperature range (70°C to 125°C derated) and delivers a total power rating of 0.4W (0.05W per resistor), making it suitable for power-sensitive designs. Its ±25ppm/°C temperature coefficient and 100V maximum voltage rating further enhance stability in fluctuating environments. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case ensures durability and thermal performance.
