TDK MLJ1005H Multilayer Inductors

TDK MLJ1005H Multilayer Inductors are low-resistance multilayer ferrite inductors designed for use in near-field communication (NFC) applications, in the LC filters of NFC circuits. The MLJ1005H inductors feature a tolerance of ±5% to minimize the loss caused by mismatched impedance with the antenna. In addition, inductor loss is controlled at the 13.56MHz communication frequency to prevent the reduction of antenna output power. The AC resistance (Rac) must be kept low and maintained even as the current is applied. By super-low loss material development, the TDK MLJ-H series achieves lower Rac during high-current applications than the 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.
