GS4B031822FDT Description

The GS4B031822FDT 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 18.2K Ohm resistance per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a -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 moderate-power circuits. Its 100V maximum voltage rating and BUS circuit designator optimize it for bus termination, voltage division, and pull-up/down applications in precision analog and digital systems.
