MURATA Chip Beads Agent Brand Series

Murata magnetic bead inductor
Murata provides a small and strong noise squelching effect of EMI squelching filter for noise removal, AC power line filter, after the completion of the integration can also be adopted with the corresponding countermeasures of ferrite core, microwave absorber, ESD protection devices to protect semiconductors from external intrusion electrostatic damage and other components that can implement noise squelching countermeasures.

MURATA magnetic beads,MURATA magnetic beads, magnetic bead inductors, can provide magnetic bead inductors for smart wearables, smart phones and other mobile devices as well as medical, electric power, automotive equipment and a wide range of applications.

Murata magnetic beads, also known as ferrite magnetic beads, are mainly divided into noise elements /EMI noise filters/electrostatic protection devices in Murata electronic components, and their main role is the effect of noise filtering.

Murata magnetic beads can be divided into three series, respectively: BLM series, DLW series, DLP series. It is applied to the circuit of common noise, common mode noise and common mode choke respectively. The following describes the functions of these three areas.

The use of capacitors inside the noise element is mostly made by transferring the noise underground, but if there is no stable ground, it has no effect. The ferrite magnetic beads can be silenced even if they are not grounded. Ferrite is inserted into the wire, and the magnetic field generated by the wire is collected into the coil by the force [μ "] that collects the magnetic flux carried by the ferrite. The magnetic energy collected in the ferrite is then consumed by converting the magnetic loss of the ferrite into heat, and the noise will not leak out. Therefore, noise can be silenced even if it is not grounded.

When noise current is superimposed on signal current. In general, the frequency of the signal current is relatively low, and the frequency of the noise current is usually relatively high. In order to reduce the noise current, it is necessary to apply a much larger impedance than the signal current, so the magnetic flux generated by the noise current is connected to the impedance signal line of the large ferrite magnetic bead, so that the noise current magnetic flux is reduced (= noise current is reduced). The same function as BLM!
