What are EMI Suppression Capacitors?
EMI suppression capacitors (also known as EMC capacitors or safety capacitors) are passive electronic components designed to reduce or eliminate unwanted electrical noise in electronic circuits. They work by filtering out high-frequency interference, ensuring that electronic devices operate reliably and comply with electromagnetic compatibility (EMC) standards. These components are crucial for applications where signal integrity and regulatory compliance are paramount.
