Feed Through Capacitors: SFUMC5000681MX0 Application Field and Working Principle

Feed through capacitors are a type of capacitor which functions as an electrical or RF shield between two or more electronics components or systems. They are often used in various applications, including audio and video applications, wireless communications, and medical applications. The SFUMC5000681MX0 is an example of a feed-through capacitor manufactured by Sager Electronics. In this article, we will explore the application field and working principle of the SFUMC5000681MX0.

Application Field

The SFUMC5000681MX0 is a surface-mount, non-polarized, RF feed-through capacitor designed for use on high speed and high frequency applications. It is designed to provide a low impedance connection between two conductors, allowing signals to pass through with minimal electrical interference. It is suitable for use in wireless communications, networking, and medical applications. The SFUMC5000681MX0 offers excellent electrical performance in both steady-state and transient conditions. Its high frequency performance is excellent and its analog values are low, making it an excellent choice for use in a wide range of applications. Additionally, its highly reliable design makes it suitable for high volume production and its low profile design makes it easy to install in tight spaces.

Working Principle

The SFUMC5000681MX0 is a high frequency, non-polarized feed-through capacitor. It operates on the principle of electromagnetic shield. It allows high frequency signals to pass through it with minimal interference while blocking low frequency and DC components. Essentially, the capacitor acts as an RF barrier, stopping low frequency components from passing through and allowing high frequency components to pass with low power loss. The SFUMC5000681MX0 is a ceramic capacitor with an integrated ferrite core. The core consists of two metal plates filled with a ferrite material. One plate is connected to the inner layer of the capacitor and the other plate is connected to the outer layer of the capacitor. The ferrite material acts as an RF shield, blocking low frequencies and attenuating high frequencies. The SFUMC5000681MX0 also has a built-in high performance metalized film capacitor, which helps to further reduce noise and reduce signal interference. This means that the feed-through capacitor is able to maintain signal integrity even when high frequency signals are present.

Conclusion

The SFUMC5000681MX0 is a surface-mount, non-polarized, RF feed-through capacitor designed for high speed and high frequency applications. It is designed to provide a low impedance connection between two conductors, allowing signals to pass through with minimal electrical interference. The SFUMC5000681MX0 operates on the principle of RF shielding, allowing high frequency signals to pass with minimal interference while blocking low frequency and DC components. It is an excellent choice for use in a wide range of applications, including wireless communications, networking, and medical applications.
