Ferrite cores, also known as ferrite beads, suppress or reduce electromagnetic interference (EMI) by channeling energy away from the circuits, wiring and connected components of an electronic device. They are a type of magnetic core, made from ceramic materials, and come in a variety of shapes and sizes.

The 2843001802 ferrite core, made of Type 1 Mn0.5Zn ferrite material, is a cylindrical bead suitable for use in low frequency, high current applications. The core is designed to reduce noise created by the flow of high current. The core responds to alternating current, absorbing energy and dissipating it as heat.

Application Field

The 2843001802 ferrite core can be used in a wide variety of low-frequency, high-current applications, including power line filters in various home appliances, such as refrigerators, microwaves and air conditioners; power feedback suppression circuits on medical instruments, safety systems, computers, gaming consoles, and other sensitive electronic equipment; battery chargers; PSU and SMPS circuits; and high-end audio equipment.

Working Principle

The 2843001802 ferrite core works by restricting the electromagnetic fields created by an alternating current. The core is made of a magnetic material, which has electromagnetic properties that cause it to absorb and redirect the electromagnetic fields. The core works by magnetising and then demagnetising the material, allowing the alternating current to flow and reducing the amount of generated noise.

The core consists of a cylindrical shape with two ends. The core is wound around a wire two or three times and the wire is then connected to two terminals. As the alternating current flows through the wire, it induces an electromagnetic field around the core, causing it to magnetise. This magnetism creates a magnetic resistance that absorbs the current, reducing noise.

When the current direction changes, the core demagnetises, allowing the current to flow and dissipating most of the energy created by the alternating current. This helps reduce the interference that is created by the alternating current and prevents it from affecting other electronic components. As the current oscillates, the core oscillates, absorbing and dissipating the unwanted energy, thus reducing EMI.

The 2843001802 ferrite core is an effective solution for suppressing EMI in low-frequency, high-current applications. It effectively restricts the flow of energy from the current, reducing interference and improving the overall performance of electronic devices.
