CIB21P470NE

Ferrite Beads and Chips are a type of passive electronic components mainly used for noise suppression for signals passing through cables and printed circuit boards. Ferrite beads and chips can be used to filter noise from high frequency signals, as well as for power line noise suppression, signal shielding, and antenna matching. One type of Ferrite Beads and Chips commonly used is the CIB21P470NE.

The CIB21P470NE is a Ferrite Beads and Chips designed for signal noise suppression and low-loss filtering of digital signals in a wide variety of applications. It is a molded chip bead and is available in an 0402 package. The CIB21P470NE is designed with a high Impedance value compared to its small size, making it ideal for applications requiring absorption of high frequency noise and thus providing a cleaner signal.

The CIB21P470NE is typically used in high speed, high performance boards to ensure noise free operation. It can be used in a range of applications including high-speed memory modules, servers, set-top boxes, and Blu-Ray/ DVD players. It is also suitable for use in smart home automation products which require accurate signal transmission and pollution control. In addition, it is also used in telecommunication and networking equipment, such as digital video broadcasting (DVB) set-top boxes and DSL modems. The CIB21P470NE is able to protect sensitive systems, such as low-power circuits, by absorbing high-frequency transients which could damage the circuit.

The working principle of the CIB21P470NE is based on its unique design which enables it to absorb high frequency noise without adding significant signal loss. The CIB21P470NE consists of a ferrite core and has a thin barrier film surrounding it. The barrier film prevents noise from being generated on the conductor side and an inner, high frequency shield absorbs any noise that is generated outside the core. The ferrite core also adds DC bias to the signal, which helps to control the power line noise. In addition, the shield also acts to reduce signal distortion and improves the signal-to-noise ratio of the system.

In summary, the CIB21P470NE is a type of ferrite beads and chips designed for low-loss filtering of digital signals in a wide range of applications. It is typically used in high-speed memory modules, set-top boxes and other digital signal processing and pollution control applications. The CIB21P470NE works by absorbing high frequency noise from the signal without adding additional losses and by providing a DC bias to reduce power line noise.
