Optocouplers
Optocouplers provide galvanic isolation between different parts of a circuit while allowing signal transmission between them. This makes these components useful in a variety of devices.
How Do Optocouplers Work?
Optocouplers are very useful components that can be applied in various circuits. Their role is to ensure galvanic isolation between two parts of a circuit while allowing information transfer. This function is possible due to their construction. An optocoupler consists of a photoemitter and a photodetector isolated from each other. The emitter, typically an LED, sends a signal that is then received by the detector. This allows optocouplers to control circuits without direct electrical current flow between them.
Applications of Optocouplers
The highly useful function of these components means that optocouplers are found in many electronic devices. They are used in various measurement devices, power supplies, and telecommunication equipment. Optocouplers are also used in robotics. Additionally, this component is used by hobbyists who engage in electronics and build their own circuits.
How to Select Optocouplers for Your Circuit?
Knowing how an optocoupler is constructed, its purpose, and its applications, you can focus on its key parameters. Proper matching of these parameters is crucial for the correct operation of the device. When selecting optocouplers for a specific circuit, consider factors such as the forward current, output voltage, and the Current Transfer Ratio (CTR). The CTR determines how much the current received is amplified relative to the current transmitted.
In our online store, you can find components with specifications suitable for various applications. Whether you are looking for a fast optocoupler or other elements in the optoelectronics category, or need components like SMD varistors to protect your circuit, our selection has the product to meet your needs.
