GS4B027870GFT Description

The GS4B027870GFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 7-resistor bussed network features a 787Ω resistance value with a tight ±2% absolute tolerance and ±1% ratio tolerance, ensuring reliable signal integrity in demanding circuits. Encased in an 8-pin narrow SOIC (SOIC-C) package, it offers a compact footprint with 4.9mm length, 5.99mm depth, and 1.45mm height, making it ideal for space-constrained designs. The thin-film technology delivers excellent stability with a low ±50ppm/°C temperature coefficient, while the ceramic substrate ensures robust thermal performance up to 125°C. Rated for 0.4W total power dissipation (0.05W per resistor) and 100V maximum voltage, it suits both industrial and commercial applications.
