EMI0805R-11

Ferrite beads and chips are mainly composed of high power smd ferrite beads and smd ferrite chips. They are widely used in many fields, such as computers, vehicles, telephone sets, and the like. The EMI0805R-11 is one of the most commonly used smd ferrite beads. It is small in size and has a wide application range. In this article, we will introduce the application field and working principle of the EMI0805R-11.

Application Fields

The EMI0805R-11 can be widely used in many different applications, such as industrial, automotive, aerospace, medical, telecom and other industries. It is a product with high power non-inductive smd ferrite beads. The EMI0805R-11 has the feature of low magnetic field leakage, high reliability, high capacitance and high power. It is mainly used to protect audio and telecommunications lines and proprietary twisted dipole cable lines from various types of electromagnetic interference. It can also be used to protect the frequency domain from signal interference in a variety of applications, such as power supplies, AC/DC converters, and LED driver systems.

Working Principle

The working principle of EMI0805r-11 is based on Faraday\'s law of induction. When an alternating current passes through a material, an induced current is created which is proportional to the changing magnetic field. The smd ferrite chips contain ferrite particles which are ferromagnetic materials such as iron oxide. As current passes through them, the small particles become magnetized and cause a high impedance barrier to the current, which is known as the skin effect. This skin effect blocks the passage of high-frequency signals and prevents them from radiating. In addition, the EMI0805R-11 can also be used to filter low frequency signals, making it efficient for applications such as the protection of telecommunications systems and data transmission lines.

The EMI0805R-11 is an indispensable component for many electronic products, it can effectively suppress EMI radiation, and it also has the effect of capacitor decoupling, can help different devices to filter interference signal. In summary, the EMI0805R-11 is a very useful smd ferrite bead with a wide range of applications.
