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 13.56MHz communication frequency to prevent the reduction of antenna output power.
The AC resistance (Rac) must be kept low and maintained even as current is applied. By super low loss material development, the new MLJ-H series achieves lower Rac during high-current applications than the existing MLJ-W series.
The use of NFC circuits is rapidly increasing in smartphones, smartwatches, wearables, and other peripheral devices. They are projected to be used in diverse ways in the realisation of a completely touchless society, including in cashless payments. TDK will expand its line of MLJ series inductors to cater to these needs and meet the needs of customers.
