GS4A031910GGT Description

The GS4A031910GGT from TT Electronics/IRC is a high-precision 4-resistor isolated network in an 8-pin narrow SOIC package, designed for demanding circuit isolation applications. Built with ceramic substrate and thin-film technology, it delivers stable performance with a 191Ω resistance value, ±2% absolute tolerance, and ±25ppm/°C temperature coefficient. The SOIC-C series offers robust 100V maximum voltage rating and 0.1W power dissipation per resistor (0.4W total), operating reliably from 70°C to 125°C. Its gull-wing termination and surface-mount design ensure compatibility with automated assembly processes. The non-automotive, non-PPAP part is housed in a rectangular ceramic case (4.9mm × 5.99mm × 1.45mm) with tight tolerances (±0.1mm height/length, ±0.2mm depth), ideal for space-constrained PCBs.

GS4A031910GGT Features

• Isolated Circuit Design: Independent resistors minimize crosstalk, critical for signal integrity.

Conclusion of GS4A031910GGT

The GS4A031910GGT excels in applications requiring high isolation, precision, and thermal stability. Its ceramic SOIC package and thin-film resistors provide superior performance over plastic-encapsulated networks, particularly in harsh environments. While non-RoHS compliant, it remains a top choice for legacy designs or niche industrial systems where reliability outweighs regulatory constraints. Engineers will value its tight tolerances, low TCR, and robust construction for critical analog circuits.
