GS4B021050DDT

GS4B021050DDT Description

The GS4B021050DDT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 7-resistor BUS-configuration array offers a 105 Ohm resistance with an ultra-tight 0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a ceramic SOIC-8 package with gull-wing SMD termination, it features a 0.4W total power rating (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for precision analog and digital circuits. The EU RoHS non-compliant device is supplied in a tube packaging for automated assembly.
