Isolators are devices used to physically isolate or separate electrical circuits or systems from each other. They are commonly used in electrical and electronic systems to prevent the flow of electric current between circuits, or to prevent the transmission of electromagnetic interference (EMI) between systems. Isolators are available in a range of sizes, styles, and configurations to suit different applications and environments. Some common types of isolators include optocouplers, which use an optical mechanism to isolate circuits; transformer isolators, which use a transformer to isolate circuits; and RF isolators, which are used to prevent the transmission of radio frequency signals between circuits. Isolators are an essential component of many electrical and electronic systems, and can help to improve safety, reliability, and performance.
