Ferrite Beads and Chips: EMI1210R-60 Application Field and Working Principle

Ferrite beads and chips are increasingly popular as a means of eliminating or reducing interference or noise caused by unwanted signals, currents and noise. The EMI1210R-60 from Murata is a ferrite chip that provides superior noise suppression performance and is particularly useful in automotive, communication, medical and other application fields. This article examines the EMI1210R-60 in more detail, looking at its application field, working principle and key features.

Application Field

The EMI1210R-60 is a high-performance ferrite bead chip designed for use in interference suppression applications. It is most effective when installed on motherboards or other PCBs, at connecting points where bleedthrough or crosstalk is likely to occur. It is notable for its ability to suppress unwanted signals and reduce interference over a wide frequency range, going from DC to peak frequencies above 3GHz. This makes it ideal for use in medical and communication systems that require several connected signal input sources. It is also useful in a range of automotive applications, including autonomous driving solutions where interference suppression is essential for reliable operation.

Working Principle

The EMI1210R-60 works by suppressing EMI using ferrite beads. This technology works by absorbing the energy of the unwanted signals, currents and noise, dissipating it as heat. To ensure effective noise suppression, the ferrite beads are configured to create what is known as an inductance loop. This loop produces a varying electromagnetic field which attracts and absorbs the energy emitted by the unwanted signals, and dissipates it, thereby significantly reducing interference and noise.

Key Features

An important feature of the EMI1210R-60 is its superior suppression performance. The ferrite beads are designed to operate over the entire DC to 3GHz frequency range, and can achieve significant improvement in noise suppression over a range of applications. The beads also feature a robust design that meets the high performance requirements of many automotive applications, with an impressive 500V insulting voltage and wide operating temperature range (from –40° to 125°C).

The EMI1210R-60 also has a range of other features that make it an attractive choice for many applications, including an ESD resistance rating of ≥4KV. In addition, the ferrite beads have a small footprint of just 0.19mm² and a low profile of only 0.1mm. This makes them ideal for use in space- and weight-constrained automotive applications.

Conclusion

The EMI1210R-60 is a high-performance ferrite bead chip designed for use in interference suppression applications. It is particularly popular in the medical, communication and automotive sectors, where its ability to reduce interference over a wide frequency range makes it an optimal solution. The chip has a robust design and offers a range of features that make it suitable for many applications, including a small form factor, low profile, ESD resistance rating and wide operating temperature range.
