EMI suppression capacitors are a specialized subset of commercially available capacitors that are designed for filtering electrical noise out of the power being supplied to the circuit. They do this by reducing the input impedance of the system for higher frequency noise.
If a conventional capacitor is used, it can fail in short condition resulting in a high current flow between lines. This type of failure can result in a fire, and it is therefore not advisable to use a conventional component. Using a class X capacitor helps to eliminate the risk of fire in the event of a component failure.
Polypropylene film capacitors are among the best choice for EMI suppression applications in industrial and automotive applications thanks to its stability and long life at harsh conditions. KEMET R53 series X2 capacitors can meet the highest THB class in a more miniaturized size than the competition.
On the other hand, Y capacitors are usually connected between line and ground. A failed Y capacitor does not activate a safety device, and there is a high risk of an electrical shock if this component fails. Just like class X capacitors, these components are further subdivided into subclasses depending on their voltage ratings.
Decoupling capacitors are essential for reducing electromagnetic interference (EMI), suppressing noise, and ensuring stable power distribution across printed circuit boards (PCBs). The evolution of decoupling techniques has been driven by the relentless pursuit of faster, smaller, and more efficient electronic systems.
Using a class X capacitor helps to eliminate the risk of fire in the event of a component failure. Common mode noise manifests itself by appearing in multiple power lines and returning in the ground line. This noise is usually identical on different power or data lines.
