Feed Through Capacitors

Feed through capacitors, also known as capacitive feed-throughs, are components used to achieve capacitive coupling between two circuits. This technology is used to control the leakage current between two lines or connector pins. This process occurs when an electrical discharge is created by an alternating electrical charge.NFM18PS474R0J3D is a type of feed-through capacitor with three connections, one each for ground, power, and control. Its compact, 1RU package contains an integrated capacitor in its circuitry to provide an excellent combined solution for optimal signal integrity and reliability. This device is suited for applications requiring high current and withstanding high voltage.It is often applied in audio frequencies, mainly due to its capability of providing simultaneous transmission of signal and power along the same line. This feature allows for higher power conversion efficiency and longer cables runs between the two circuits.The NFM18PS474R0J3D also features a single-pole switching action, which makes it ideal for switchable, driveable applications. It serves as a median for providing a solution to a complex electronic load balancing. This component could be connected in series in order to achieve higher capacitance. Its unitary construction eliminates the need for extra shielding and reduces assembly and installation time. Additionally, it meets mil-spec standards which make it suitable for hi-rel applications.The working principle of this component is to create an electrical circuit between two conducting surfaces. This functionality is mainly achieved by placing a dielectric between the two surfaces. The dielectric can be either an insulator, such as air or a vacuum, or it can be a semi-conductor material, such as a ceramic. The dielectric acts as part of an electrical capacitor, which works by storing an electrical charge, creating a voltage difference between the two conducting surfaces.When a current flow passes through the component, it is used to create an electric field between the two surfaces, which reduces the flow of current by creating an electrical capacitance between the two. This creates a barrier, which stops the current from completely passing through the component.In general, the NFM18PS474R0J3D is a feed through capacitor used in various high power applications. It helps in creating capacitive coupling which helps in reducing current leakage and maintaining signal integrity. It features a single-pole action which makes it suitable for switchable, driveable applications. Its construction also allows for quick assembly and installation.
