FAQs about How to use capacitors for isolation protection
How does a capacitive isolator work?
At its core, a capacitive isolator consists of two capacitors connected in series, with an isolation barrier in between. When an AC voltage is applied to one of the capacitors, it induces a charge in the other capacitor through the barrier, thus transmitting the signal.
Can a capacitor be used to isolate a DC/DC converter?
Capacitive isolation is most often associated with replacing optocouplers or transformers when transmitting data across an isolation barrier. It is not usually associated with power isolation. Helix Semiconductors has recently developed a technique that uses capacitors to provide voltage isolation in DC/DC converters.
How to choose a capacitive isolator?

What are the limitations of a capacitive isolator?
Despite their versatility, capacitive isolators come with certain limitations. Since capacitive coupling relies on changes in voltage to transmit signals, they may not be suitable for transmitting low-frequency or DC signals. Moreover, capacitive isolators may exhibit high impedance, which can influence the signal's amplitude and quality.
What is the difference between a capacitive isolator and an optocoupler?
nd industrial power. Capacitive isolators are not susceptible to magnetic noise but can maintain high data rates and keep p wer consumption low. Capacitive isolation can also transfer signals bi-directionally, while optocoupler
