GS4A0127R4JFT Description

The GS4A0127R4JFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 4-resistor network is housed in an 8-pin narrow SOIC (SOIC-C) package, featuring isolated elements to minimize crosstalk and ensure independent operation. With a resistance value of 27.4Ω and a tolerance of ±5%, it offers excellent accuracy, further enhanced by a ratio tolerance of ±1% for matched pairs. The thin-film technology ensures low noise and high stability, while the ±100ppm/°C temperature coefficient guarantees consistent performance across a wide operating range of -70°C to +125°C. Its 100V maximum voltage rating and 0.1W power rating per resistor (0.4W total) make it suitable for demanding environments.
