SFBML5000222MX1

Feed Through Capacitors

The SFBML5000222MX1 is a type of feed through capacitor, which is a passive electronic component composed of a dielectric material and two sets of electrodes. In the case of the SFBML5000222MX1, two parallel plates are encapsulated in a ceramic body that contains a dielectric material. This creates a capacitor where electrons flow from one set of plates to the other. When the capacitor is connected in series with an electrical load, the capacitance of the capacitor will tend to pass DC current while blocking AC current.

Application Field

The SFBML5000222MX1 feed through capacitor is primarily used in the field of automotive electronics. For example, it is used in ignition systems, as well as in power and engine control systems. Its small size also makes it ideal for high frequency radio circuitry. In addition, it can be used in filtering and bypassing, where it prevents interference from affecting the signal. It is also used in computers and consumer electronics to reduce noise in circuit designs.

Working Principle

The feed through capacitor works through capacitance. The two sets of plates surrounded by a dielectric material form a capacitor that allows electrical current to flow across it. When an electrical charge is applied to the capacitor, the plates become charged with electrons, creating a voltage difference between them. The current then flows through the dielectric material between the plates. This effect is most pronounced when the frequency of the applied voltage is at or near the resonant frequency of the capacitor, as the capacitance and consequently the current passing through the capacitor is maximized.

The SFBML5000222MX1 feed through capacitor is designed for high frequency applications and is capable of operating at frequencies up to 10 MHz. Its low ESR and low self-resonant frequency make it an ideal choice for a wide range of electrical applications requiring bypassing or filtering.
