GS4B021331FT Description

The GS4B021331FT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package. Designed for precision applications, it features a 1.33KΩ resistance value with a tight ±1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. The thin-film technology delivers superior accuracy and reliability, while the ceramic case enhances thermal and mechanical durability. With a 0.4W total power rating (0.05W per resistor) and a 100V maximum voltage rating, this network is ideal for demanding circuits requiring consistent signal integrity.
