GS4A025490JGT Description

The GS4A025490JGT 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 549Ω 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 ±50ppm/°C temperature coefficient, it ensures minimal resistance drift, while its 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating provide robust performance in compact designs. The gull-wing termination and surface-mount (SOIC) package facilitate easy PCB integration.
