·Development of Low Loss High Current Layered Inductors

The Fifth Ring Road has been developed asNFCLow loss and high current multilayer inductors supported by coilsMLJ1608The series has been released from4Mass production will begin from this month onwards.

In recent years, with the high performance of smartphones, tablets, and digital camerasNFCThe number of electronic devices in circuits is gradually increasing. InNFCIn the circuit, controlICInstalled between the antennaLCThe filtering circuit requires the coil used here to be a narrow tolerance inductor and to have13.56MHzUnder the frequency of communicationHigh-Qcharacteristic. Moreover, due to the flow during communication100～300mAThe communication signal between the left and right sides needs to maintain stable characteristics even when powered on.

MLJ1608The series uses newly developed low loss technologyFerrite materialWhen the communication signal is energized, it also achieves low loss characteristics higher than coils of the same shape. In addition, the overlapping characteristics of ferrite materials have also been improved, as they flow throughNFCThe current of the circuit is the largest300mAAt the same time, it can also ensure the same characteristics as the winding coil. Of course, it also ensures the narrow tolerance of the inductorHigh-QMagnetic shielding characteristics have become a requirementNFCProducts that meet all the characteristics required by the coil.

The range of inductance is expanded to160nH～560nHAt the same time, the Fifth Ring Road is also developing targets for low power consumptionNFC-ICRequirements for miniaturizationMLJ1005seriesinductor.
