GS4B032802FBT Description

The GS4B032802FBT from TT Electronics/IRC is a high-precision 7-resistor thin film network in an 8-pin SOIC package, designed for surface-mount applications. With a 28K Ohm resistance per element and a tight 1% tolerance, this network ensures reliable performance in precision circuits. The ceramic case style and thin film technology provide excellent stability, with a low ±25ppm/°C temperature coefficient, making it suitable for environments with temperature fluctuations (70°C to 125°C). Rated for 0.4W total power dissipation (0.05W per resistor) and a maximum voltage of 100V, it is ideal for signal conditioning, voltage division, and bus termination in industrial and consumer electronics.

GS4B032802FBT Features
