Ferrite Beads and Chips

Ferrite beads and chips are electronic components meant to isolate and filter out high-frequency noise from signals coming from digital and analog circuits. Many products, such as laptop computers, cell phones, and audio systems, are designed with ferrite beads and chips to reduce electromagnetic interference (EMI).

LI0201A301R-10 ferrite beads and chips are one of the most efficient and economical solutions currently available for EMI filtering and suppression. These ferrite beads are well suited for use in telecommunications products, automotive, industrial and consumer applications.

Application Field

LI0201A301R-10 ferrite beads are a type of multi-layer monolithic type, suitable for many applications including interference suppression of cable transmission lines, amplifiers, switching power supplies, and other digital or analog digital electronic products. These ferrite beads are especially good for differential signal lines, such as High-Definition Multimedia Interface (HDMI) lines, and Serial Advanced Technology Attachment (SATA), hard drive cables, USB cables or other cables with high-speed digital data signals.

These ferrite beads help to reduce signal coupling and interference as well as provide protection against EMI for the digital line itself. They can also be used to reduce EMI from the ESD counter on wireless devices such as mobile and cellular phones.

Working Principle

LI0201A301R-10 ferrite beads consist of two layers of conductive material- an inner core and an outer core- surrounded by an insulating layer of ceramic. The inner core is a mixed-phase material while the outer core is a low-permittivity dielectric material.

The mixed-phase material creates a magnetic field which induces electrical currents in the outer core of the bead. When the frequency of an incoming signal reaches a certain threshold value, a changing magnetic field is created which interacts with the existing field and produces a significant reduction in the signal strength.

In this way, the ferrite bead helps reduce the level of EMI. In addition, these beads provide excellent performance over a wide frequency range, eliminating both high and low-frequency noise from signals.

LI0201A301R-10 ferrite beads are an ideal choice for a wide range of applications due to their low cost and excellent performance. Their compact size prevents them from taking up any extra space in the device they are used in, allowing for easier integration into existing components.

The robust construction of LI0201A301R-10 ferrite beads ensures long-term durability and reliability. If used properly and in accordance to manufacturer specifications, these beads will provide superior performance and protection for many years.
