MKP capacitors are metallized polypropylene film capacitors whose operating principle is based on their internally metallized film structure. Each of the two electrodes of an MKP capacitor is coated with a layer of metallic aluminum, separated by a layer of polypropylene film, and then connected to the external circuit via copper foil leads also coated with metallic aluminum. When an MKP capacitor is connected in a circuit, the metallized layers on its two electrodes effectively serve as the capacitor’s electrodes, while the polypropylene film in between acts as the capacitor’s dielectric.
When the circuit is operating, MKP capacitors store electric charge and release it when needed, thereby stabilizing the circuit’s voltage and current. MKP capacitors boast excellent frequency response characteristics and low losses, effectively suppressing high-frequency interference and playing a crucial role in applications such as filtering, coupling, and decoupling. At the same time, MKP capacitors also offer advantages such as high-temperature stability and long service life, enabling them to operate reliably under a wide range of demanding working conditions.
In summary, MKP capacitors, with their reliability, high performance, and environmentally friendly characteristics, are widely used in various electronic devices and circuits, playing an important role in enhancing circuit stability and performance.
