GS4B037502FDT Description

The GS4B037502FDT from TT Electronics/IRC is a high-precision 7-resistor thin-film network in an 8-pin SOIC package, designed for surface-mount applications. It features a 75K Ohm resistance per element with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. The ceramic case and gull-wing termination provide robust mechanical and thermal stability, while the 0.4W total power rating (0.05W per resistor) makes it suitable for compact, power-sensitive designs. With a 100V maximum voltage rating and ±0.1mm height/length tolerances, this network is ideal for precision analog and digital circuits.
