GS4B021050GT

GS4B021050GT Description

The GS4B021050GT from TT Electronics/IRC is a high-reliability ceramic resistor network designed for precision applications in demanding electronic circuits. This 7-resistor bussed (BUS) network features a 105Ω resistance value with a tight ±2% absolute tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in an 8-pin narrow SOIC (SOIC-C) package, it offers a compact 4.9mm × 5.99mm × 1.45mm footprint with gull-wing terminations for secure surface-mount assembly. The thin-film technology provides superior accuracy and power handling, with a 0.05W (1/20W) rating per resistor and a total power rating of 0.4W. Rated for 100V maximum voltage, this network is ideal for signal conditioning, voltage division, and bus termination in industrial and consumer electronics.
