GS4B0154R9JDT Description

The GS4B0154R9JDT 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 technology. With a 54.9Ω resistance per element and a ±5% absolute tolerance, this ceramic-based network ensures reliable performance in demanding environments. Its ±100ppm/°C temperature coefficient and 0.05W (1/20) power rating per resistor make it suitable for circuits where thermal stability and power dissipation are critical. The SOIC-C series construction offers robust mechanical integrity, with a compact footprint (4.9mm length × 5.99mm depth × 1.45mm height) and gull-wing termination for secure surface mounting. Rated for 100V maximum voltage and 125°C operating temperature, it is ideal for industrial and instrumentation applications.
