Ferrite Beads and Chips

Ferrite beads and chips are a type of inductor composed of a ferrite core seed with conductive windings wound around it. A ferrite is a type of ceramic material made of a mixture of iron oxides. These materials have a high electrical resistance at low frequencies, but at higher frequencies they decrease resistance and reduce electromagnetic interference. Ferrite beads and chips are used in a variety of electronic components, including power supplies, audio equipment, computers, cell phones, and other electronic systems.

The MPZ2012S221AT000 device is a ferrite bead and chip used in applications requiring minimal insertion loss and high attenuation of forward-reflected signals. This device is a 0402 size package, measuring just 0.4mm by 0.2mm, making it suitable for high-frequency signals. The MPZ2012S221AT000 has an impedance range of between 12 ohms and 20 Ohms, with a rated current of 0.9 Amps.

Working Principle

The working principle of the MPZ2012S221AT000 ferrite chip is based on Faraday’s law of induction. When a varying current flows through the conductive windings that wrap around the ferrite bead or chip, a varying magnetic field is induced within the ferrite. This varying magnetic field induces an opposing current in the windings, which resists the direct current, thus providing a degree of electromagnetic interference (EMI) protection. The actual amount of protection that is obtained is largely determined by the properties of the ferrite material and the characteristics of the inductor.
