Ferrite Beads and Chips

Ferrite beads and chips are components which are used in computer and electrical systems that provide magnetic shielding around cables and wires. The 28L0138-40R ferrite bead and chip is one example of a ferrite bead and chip component.

Application Field

28L0138-40R ferrite beads and chips are mainly used for shielding high frequency signals in order to reduce electromagnetic interference (EMI). They are specifically designed for high frequency, low-current applications and offer excellent protection from EMI and magnetic interference for data and power line cables. These components are ideal for medical device applications, pacemakers, measured instruments, bandwidth signal transmission and more.

Working Principle

The 28L0138-40R ferrite beads and chips work through a simple principle. The bead and chip have a cylindrical core, which is surrounded by a ferrite material. The core is normally made from permeable ferrite material. This material captures, stores, and releases electrical energy as it passes through the core and the material. This process helps to attenuate the EMI and magnetic interference.

The bead also acts as a low-pass filter, damping any intruding high-frequency power signals as they pass through the core. This helps to reduce the magnitude of the emitted EMI signals, making them harmless to other equipment in the vicinity. The chip also reduces the impedance of the circuit, making it easier for the signal to flow through.

The 28L0138-40R ferrite bead and chip also provide EMI shielding from both the interior and exterior of the system. On the interior side, the bead and chip absorb any EMI signals from the components and dissipate them. On the exterior side, the chip acts as a shield, reflecting and trapping any EMI signals from outside sources.

Advantages

The 28L0138-40R ferrite bead and chip have several advantages when compared to other forms of EMI protection. These components are relatively small, making them easy to install in systems. They also require little power compared to other EMI protection methods. In addition, they are relatively inexpensive and provide quick and reliable EMI protection.

The 28L0138-40R ferrite bead and chip also offers several features that make it an ideal choice for various applications. These components are extremely durable, making them suitable for long-term use. They are also designed to perform equally well even under fluctuating temperatures and can withstand the effects of corrosion.

Conclusion

The 28L0138-40R ferrite bead and chip provides robust EMI protection and ensures that data and power lines are properly shielded. These components are easy to install, require little power, and offer excellent protection from EMI and magnetic interference. They are also durable and suitable for various applications, making them an ideal choice for shielding data and power cables.
