GS4A0238R3JDT Description

The GS4A0238R3JDT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. Housed in an 8-pin narrow SOIC package, it features four isolated thin-film resistors with a resistance value of 38.3Ω and a ±5% absolute tolerance. The device operates over a wide temperature range of 70°C to 125°C with a low temperature coefficient of ±50ppm/°C, ensuring stable performance under thermal stress. Its 0.1W (1/10) power rating per resistor and 100V maximum voltage rating make it suitable for demanding circuits. The SOIC-C series construction provides robust mechanical stability, while the gull-wing termination ensures reliable surface-mount assembly.
