GS4A0190R9GGT

GS4A0190R9GGT Description

The GS4A0190R9GGT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding environments. This 8-pin Narrow SOIC device features four isolated thin-film resistors, each with a resistance value of 90.9Ω and a tight ±2% absolute tolerance. The network operates over a wide temperature range of -70°C to +125°C, with a ±100ppm/°C temperature coefficient, ensuring stable performance under thermal stress. Encased in a rectangular ceramic SOIC package, it offers excellent thermal and mechanical stability, with a 0.1W power rating per resistor (0.4W total). Its gull-wing termination and 1.27mm terminal pitch facilitate reliable surface-mount assembly, while the 100V maximum voltage rating makes it suitable for high-voltage circuits.
