GS4B012490JDT Description

The GS4B012490JDT 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. Encased in a ceramic substrate, it offers superior thermal stability with a ±100ppm/°C temperature coefficient and a 5% tolerance on its 249Ω resistance value. Rated for 0.4W total power dissipation (0.05W per resistor), it operates reliably across a -70°C to +125°C temperature range, with derated performance up to 125°C. Its gull-wing termination and 1.27mm terminal pitch ensure compatibility with standard SMT processes. The SOIC-C series construction provides robust mechanical integrity, with tight dimensional tolerances (±0.1mm height/length, ±0.2mm depth). Non-compliant with EU RoHS, it is ideal for industrial and non-automotive environments.
