GS4B032490JGT

GS4B032490JGT Description

The GS4B032490JGT 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. This ceramic-based resistor network offers a 249Ω resistance value per element with an absolute tolerance of ±5% and a ratio tolerance of ±2%, ensuring consistent performance in matched circuits. Its ±25ppm/°C temperature coefficient provides excellent thermal stability across the -70°C to +125°C operating range, making it suitable for harsh environments. The SOIC-C series construction features gull-wing terminations for reliable surface-mount assembly, with a compact footprint (4.9mm length × 5.99mm depth × 1.45mm height) and 1.27mm terminal pitch for high-density PCB layouts. Rated for 100V maximum voltage and 0.4W total power dissipation, it balances durability with space efficiency.
