MLJ1005H Multilayer Inductors

TDK’s MLJ1005H low-resistance multilayer ferrite inductors were developed and designed for use in near field communication (NFC) applications. The inductors' intended use is for the LC filters of NFC circuits. Inductors must have narrow tolerances to minimize the loss caused by mismatched impedance with the antenna. TDK offers this line of inductors featuring a tolerance of ±5% to meet this need. In addition, it is important to control inductor loss at the 13.56 MHz communication frequency to prevent the reduction of antenna output power. The AC resistance (R_AC) must be kept low and maintained even as current is applied. By super-low loss material development, the MLJ-H series achieves lower R_AC during high-current applications than the existing MLJ-W series. With NFC circuit use rapidly increasing in smartphones, smartwatches, wearables, and other peripheral devices, they are projected to be used in diverse ways in the realization of a completely touchless society, including in cashless payments.
