GS7A0228R7GGT Description

The GS7A0228R7GGT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and robust thermal performance. Housed in a 14-pin narrow SOIC package, this 7-resistor isolated network offers a 28.7Ω resistance per element with a tight ±2% absolute tolerance and ±2% ratio tolerance. Its thin-film technology ensures low noise and high accuracy, while the ±50ppm/°C temperature coefficient guarantees minimal resistance drift across a wide operating range of -70°C to +125°C. With a 0.1W power rating per resistor (0.7W total) and a 100V maximum voltage rating, this component is engineered for reliability in demanding environments.
