What are Feed Through Capacitors?

Feed Through Capacitors are electricity-functioning devices used to transfer high-frequency signals between points A and B within a circuit. Their purpose is to filter out electromagnetic interference and reduce signal 2 noise, whilst maintaining signal integrity. Their design consists of a central core, which contains a dielectric material, usually ceramic, or plastic and two metalized terminations. These metalized terminations are usually copper or silver. They are connected to two leads, like a capacitor, which run through a hole in the substrate.

SBSMP5000223MXB Application Field and Working Principle

The SBSMP5000223MXB model is a device designed for applications that require extremely high-frequency signals to be transmitted with minimal signal interference. It has a higher breakdown voltage than similar devices, up to 1250V, and a frequency of up to 1200MHz. It is constructed from a central ceramic dielectric core, with copper or silver-plated terminations and a polystyrene substrate.

The working principle of the SBSMP5000223MXB is relatively simple. When an alternating current passes through the device, wires form between the metal plated terminations and the dielectric core. These wires act like chokes, causing high-frequency signals to pass through the device without being attenuated or blocked. Low-frequency signals, however, do not pass through as effectively, since they require more energy to pass through the device. This helps reduce electromagnetic interference.

Benefits of Feed Through Capacitors

Feed Through Capacitors have a few advantages over traditional capacitors. Firstly, they can handle higher frequencies, since low-frequency signals are filtered out by the choke wires. Secondly, they have higher breakdown voltage ratings, enabling them to be used in circuits that require higher voltage levels. Finally, they can be mounted directly onto the substrate, saving time and expense on installation.

Overall, the SBSMP5000223MXB model of Feed Through Capacitors is a reliable and effective device that helps to reduce noise and maintain signal integrity in high-frequency applications. It is a low-cost and easy to install solution, and is well suited for high-frequency applications such as medical electronics, wireless communications, automotive electronics, and military applications.
