Ferrite Beads and Chips: 742792015 Application Field and Working Principle

Ferrite beads and chips are components provided by electrical and telecom companies that play a role in EMI (electromagnetic interference) mitigation techniques. They are small bits of ferrite material designed to reduce the intensity of high-frequency radio waves. In short, these components act as high-frequency noise filter devices, protecting against unintentional radiation in wired or wireless systems, networking devices, and semiconductors.

They come in many different sizes and shapes. The most common types are cylindrical and surface-mounted, and come in various sizes. The 742792015 from Murata Electronics is a low-profile chip-type ferrite bead that acts as an EMI suppression filter in applications where a higher insertion loss is required.

Application Field

The 742792015 are specifically designed for use in mobile phones, other handheld devices, and other portable electronics. The device is a low-cost, high-performance component that offers excellent EMI suppression with minimal package size, allowing for more efficient design optimization and layout for a wide range of mobile devices. It can also be used as a general-purpose digital or analog filter in the signal paths of digital signal processing, which improves system performance and reduces costs.

The 742792015 is a two-terminal noise suppression component that can be used in product designs for consumer, automotive, and medical applications. It is ideal for the traditional board and component designs seen in notebooks, digital cameras, phones and wireless applications.

Working Principle

The 742792015 works on the principle of impedance. It has the ability to reduce the flow of common-mode and differential-mode currents to a minimum while minimizing unwanted high-frequency noise in sensitive electronic circuits. This is achieved using an effective EMI suppression filter that consists of a high-frequency impedance network.

The 742792015 has a low profile design of only 1.2mm, which allows for it to fit into compact spaces and be placed directly on the PCB (printed circuit board). It also has an operating temperature range of -40° to +125°C, making it suitable for use in a variety of environments.

Additionally, the component features an effective noise suppression filter with a turn-on voltage of ~0.3V and a turn-off voltage of ~3V. This ensures that the component works consistently and reliably over a wide temperature range.

The 742792015 also comes with a number of other features. These include a tight 100% screening process, a built-in self-test (BIST) feature and low impedance values to ensure maximum efficacy. As well, the component boasts superior EMI protection and is designed to keep the electrical environment in the application area clean.

Conclusion

In conclusion, the 742792015 from Murata Electronics is a high performance Ferrite Bead and Chip component that is particularly designed for mobile phones, other handheld devices, and other portable electronics. It has excellent EMI suppression capabilities and features a low-profile design of only 1.2mm, as well as an operating temperature range of -40° to +125°C. With its tight 100% screening process, built-in self-test (BIST) feature, and low impedance values, the component offers superior EMI protection and ensures that the electrical environment in the application area remains clean.
