Mercury content in capacitors
Our products revolutionize energy storage solutions for base stations, ensuring unparalleled reliability and efficiency in network operations.
A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate on the conductors.
