GS4B019091JFT Description

The GS4B019091JFT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package, designed for precision applications requiring stable thin-film resistance. With a 9.09KΩ resistance value and ±5% absolute tolerance, it ensures reliable signal conditioning and voltage division. The ceramic case style and SOIC package offer robust thermal and mechanical stability, while the gull-wing termination facilitates secure surface mounting. Rated for 100V maximum voltage and 125°C maximum operating temperature, it operates derated from 70°C to 125°C, making it suitable for demanding environments. Its ±100ppm/°C temperature coefficient and 0.4W total power rating (0.05W per resistor) ensure consistent performance under varying thermal conditions.

GS4B019091JFT Features

• Bussed Network Design: Simplifies circuit layout with shared connections, reducing PCB complexity.
• Thin-Film Technology: Delivers high precision (±5% tolerance) and low noise for sensitive analog/digital circuits.
• Robust Construction: Ceramic substrate and SOIC package enhance durability and heat dissipation.
