    Get a 4-step process for selecting the right optocoupler. This guide covers opto coupling fundamentals, key parameters like CTR, and matching output types to your load. As engineers and designers, you face a major challenge: selecting the right optocoupler from thousands of. Simply put, optocouplers (or opto-isolators) are electronic components that transfer electrical signals between two isolated circuits using light, ensuring safety and noise reduction. Unlike transformers or capacitors, which can only transfer AC signals across the isolation barrier, optocouplers can. Optocouplers are popularly perceived as being “slow” and are thus excluded from many designs in which they could potentially serve as excellent solutions to difficult design challenges.
