GS4A0228R7JGT Description

The GS4A0228R7JGT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding environments. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a resistance value of 28.7Ω and a ±5% absolute tolerance. The device operates over a wide temperature range of -70°C to +125°C, with a ±50ppm/°C temperature coefficient, ensuring stable performance under thermal stress. Its 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating make it suitable for high-reliability circuits. The SOIC-C series construction offers robust ceramic case protection, while the gull-wing termination ensures secure surface mounting.
