GS4A038450JFT Description

The GS4A038450JFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a resistance value of 845Ω and a ±5% absolute tolerance. The device operates within a wide temperature range of -70°C to +125°C, making it suitable for harsh environments. With a ±25ppm/°C temperature coefficient and ±1% ratio tolerance, it ensures minimal drift and excellent matching accuracy. The SOIC-C series construction offers robust ceramic substrate reliability, while the gull-wing termination enables secure surface-mount (SMD) assembly.
