GS4A0361R9DT

GS4A0361R9DT Description

The GS4A0361R9DT from TT Electronics/IRC is a high-precision 4-resistor network in an 8-pin narrow SOIC package, designed for isolated circuit applications (ISOL). Featuring 61.9Ω resistance per element with a tight ±0.5% tolerance and ±25ppm/°C temperature coefficient, this thin-film ceramic-based network ensures stable performance across a wide temperature range (70°C to 125°C). Its SOIC-C series construction offers superior reliability with a 0.1W power rating per resistor (0.4W total) and a 100V maximum voltage rating, making it suitable for demanding environments. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case enhances thermal and mechanical durability.
