Ferrite Beads and Chips

2508051216Y0 is a ferrite bead packaged in a 0402 case size, with a rated current of 16 Amps. The type is a Low-Pass Filter with a 120pF capacitance, suitable for a variety of applications. This type of component is used to reduce unwanted noise, often in high speed applications. It has a high-frequency response cut-off of 1.2MHz.

Application Field

This type of ferrite bead is used in many electronic devices, including video equipment, radios, and smart devices. It is also used in inverter equipment, medical equipment, and instrumentation equipment. It is well known for its ability to reduce high frequency noise in high-speed and power switching applications.

In particular, the 2508051216Y0 is used to reduce noise interference in high-speed digital interfaces, such as USB3.0, DisplayPort, HDMI, Ethernet, Serial ATA, and other high-speed communication protocols. It is also used in power supplies, allowing them to pass EMI testing. It is often used in combination with other components, such as capacitors and coils, to further reduce unwanted noise.

Working Principle

The ferrite bead is composed of powdered ferrite which is combined with a core material such as iron. The powdered ferrite absorbs and dissipates high-frequency noise, while the core material provides a low-impedance path for high currents. The bead works by presenting a high impedance to high-frequency noise, but a low impedance to passing DC or low-frequency signals.

The 2508051216Y0, like other ferrite beads, has a porous core and outer wall. This allows it to absorb incoming high-frequency noises and dissipate them as heat. As the frequency of the noise increases, the bead becomes increasingly effective, until it reaches its cutoff frequency of 1.2MHz.

The absorptive properties of the ferrite bead also make it useful in suppressing radiation and damping high-impedance vibrations. This makes it a useful device in a number of engineering applications.

In addition to the absorptive properties of ferrite beads, they also possess inductive properties. Although the inductance of the 2508051216Y0 is very low, it can still reduce harmonics and improve power factor in high-speed applications.

Conclusion

The 2508051216Y0 is a versatile ferrite bead used in many electronic applications. It is able to reduce high-frequency noise, and its inductive properties can help to improve power factor. The bead is also widely used in video equipment, radios, and smart devices.
