GS4A024221JGT Description

The GS4A024221JGT from TT Electronics/IRC is a high-performance 4-resistor isolated network in an 8-pin narrow SOIC package, designed for precision applications. Built with ceramic substrate and thin-film technology, it offers a 4.22KΩ resistance per element with an absolute tolerance of ±5% and ratio tolerance of ±2%. The device operates within a wide temperature range of -55°C to +125°C, derated up to 125°C, and features a low TCR of ±50ppm/°C for stable performance under thermal stress. With a 100V maximum voltage rating and 0.1W power dissipation per resistor (0.4W total), it is housed in a compact 4.9mm x 5.99mm x 1.45mm SOIC case, making it suitable for space-constrained designs.
