The selection process is divided into four stages: After specifying the circuit structure and the capacitor bank’s total capacitance, the developer must then enter the charging voltage and the maximum ambient temperature of the PTC inrush current limiter. After this has been done, the tool displays a list of suitable components for the user, and if a parallel connection is required, the number of components required is also shown.

The inductors’ intended use is for the LC filters of NFC circuits. It is necessary for inductors to 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.

Film capacitors use a thin plastic film as the dielectric that separates multiple metal electrodes. The electrodes are either deposited directly on the film (metallization) or are built from separate metal foils. The plastic metal sandwich is wound on a bobbin, and a terminal contact layer is deposited to connect all of the individual capacitor layers in parallel effectively.
