Ferrite cores are an essential component of many electrical engineering applications. They are used to shield the magnetic field and reduce EMI emissions, and reduce electrical noise. The 28B0686-200 ferrite core is a high performance model designed specifically for these kinds of applications. In this article we will discuss the application field and working principle of the 28B0686-200.

Application field

The 28B0686-200 ferrite core is a high-performance device that is ideal for a variety of applications such as power line filter, power cord or cable shielding, and electronic equipment shielding. It is suitable for use in high-frequency circuits, power supplies, appliances, and other high-current applications.

This ferrite core is designed for power lines up to 35A, and it has a high impedance of 0.1Ω. It is also suitable for use in digital circuits with low bit rates (up to 1Mbps) and for the suppression of higher frequency noises. The device has a high thermal capacity, which makes it suitable for applications that require heat dissipation.

Working Principle

The 28B0686-200 ferrite core operates by redirecting the magnetic fields around it. It does this by collecting and trapping the magnetic flux, which creates a “shield” that prevents external electromagnetic interference from penetrating into the circuit. The device also reduces EMI radiation from inside the circuit.

The ferrite core works by taking in the magnetic flux that is generated by the current. This flux is then redirected so that it does not interact with other components or interfere with external devices. The core can also absorb EMI radiation, which helps reduce power supply noise and other electrical interference.

The 28B0686-200 includes a flexible rubber sleeve that helps to dampen vibration and reduce the amount of noise that is generated. This increases the reliability of the device and ensures that it functions correctly in the application.

Conclusion

The 28B0686-200 ferrite core is a high-performance device used in a variety of applications. It is designed to reduce EMI emissions and electrical noise, and is suitable for use in high-frequency circuits, digital circuits, and power supplies. The device works by redirecting the magnetic flux and trapping external electromagnetic interference to reduce EMI radiation. The core includes a flexible rubber sleeve to help dampen vibration and ensure correct functioning.
