Ferrite Beads and Chips

PMH0805-301 is a type of ferrite bead or ferrite chip used in a wide variety of applications.Ferrite nanoparticles are made from a mix of ceramic oxides, typically manganese, zinc, iron and nickel. Depending on the mix, ferrite nanoparticles can be used for electrical insulation, a coating with electrical conductivity, or a magnet.These types of nanoparticles are often used in consumer electronics to provide decoupling of localized electromagnetic Interference (EMI) between differing components, such as plastic, ceramic, metal, etc. They can also be used to provide EMI shielding of sensitive components, reduce EMI from radiators, help channel EMI to ground, or for high- and low-pass filters.When used as a ferrite bead, the PMH0805-301 is made in a cylindrical shape and functions as a high-frequency choke. It limits the flow of current through a circuit, blocking high frequencies while allowing low frequencies to pass. The PMH0805-301 also acts as an electromagnetic interference (EMI) shield. It can be placed near a component with EMI issue to reduce the amount of EMI that it receives.The PMH0805-301 is also available as a ferrite chip, which functions as a low-pass filter. Ferrite chips have a higher impedance than ferrite beads and better block high-frequency interference. They also dissipate more heat than ferrite beads, allowing them to work under higher temperatures and in more powerful applications.Ferrite beads and chips are used in many different applications, including automotive, medical, consumer electronics, and more. They are used to reduce the amount of EMI that is present in nearby components, as well as provide filtering, impedance matching, and more. The PMH0805-301 is a versatile and commonly used ferrite component that can be used in a variety of applications.
