　　Basic parameters of linear optocouplers

　　1. Response time: The response time of an optocoupler refers to the time when the output signal starts to change after the optical signal reaches the optocoupler. Optocouplers with short response times are suitable for applications such as high-speed transmission and fast switching.

　　2. Transmission ratio: Transmission ratio refers to the ratio between output current and input optical power. The higher the transmission ratio, the higher the transmission efficiency of the optocoupler.

　　3. Bandwidth: Bandwidth refers to the frequency range that optocouplers can transmit. The wider the bandwidth, the better the transmission performance of the optocoupler at high frequencies.

　　4. Leakage current: Leakage current refers to the leakage current at the output terminal when the optocoupler is not working. The smaller the leakage current, the better the insulation performance of the optocoupler.

　　5. Voltage resistance: Voltage resistance refers to the maximum operating voltage that an optocoupler can withstand. The higher the withstand voltage, the more the optocoupler can operate at higher voltages, improving the safety and reliability of the system.

　　The selection requirements for linear optocouplers involve factors such as operating frequency range, output current, isolation voltage, and temperature characteristics. Meanwhile, in the selection process, it is necessary to consider the basic parameters of the optocoupler, such as response time, transmission ratio, bandwidth, leakage current, and withstand voltage. Reasonably selecting linear optocouplers and matching parameters according to application requirements can ensure the stability and reliability of the system, and improve the performance of the entire system.
