EXC-ELSA35

Ferrite beads and chips are components that play a vital role in electronic circuitries, and their popularity is growing. Among those components, the EXC-ELSA35 has been widely recognized as a reliable solution for managing power supply, signal integrity and interference management problems. This article will discuss the application field and working principle of EXC-ELSA35.

Application Field
EXC-ELSA35 is mainly used as a common-mode noise filter on power lines. Under normal conditions, it can help transfer power from the power supply to the destination, and it also serves as an interference filter. It can be installed on power lines, communication lines, signal lines or data lines as a shield to filter out high frequency noise, thus improving the signal integrity and power delivery efficiency. Furthermore, it not only helps reduce hardware costs but also reduces the complexity of PCB design.

Working Principle
The EXC-ELSA35 is a low pass filter, which consists of a ferrite core surrounded by two copper coils. Its operation relies on the principle of inductance, which refers to the production of an electromotive force in a coil that is maintained by a changing magnetic field. When power is supplied to two leads of the filter, a changing magnetic field is created between the copper coils, causing a frequency-dependent induction on the ferrite core. This produces the effect of filtering out high frequency signals over a certain range while allowing low frequency signals to stay intact.

The EXC-ELSA35 also has two distinctive features that set it apart from the competition: the “Frequency Selective” option and the “High Frequency Power Interference Prevention” option. The “Frequency Selective” option is a feature that allows users to customize the filtering range according to their needs, while the “High Frequency Power Interference Prevention” option enables users to block out high frequency power noise, thus preventing interference.

The EXC-ELSA35 is a reliable solution for managing power supply, signal integrity and interference management problems. Its application field and working principle have been explained in this article. It can serve as an interference filter, which helps reduce hardware costs and the complexity of PCB design, while providing excellent signal integrity and power delivery efficiency.
