As electronic devices become faster and operate at higher frequencies, capacitors used for noise filtering and decoupling applications require even lower ESL (Equivalent Series Inductance) characteristics.
Additionally, in automotive electrical systems, there is an increasing demand for low-ESL type products to improve safety and comfort and to meet the demands of infotainment.
This Solution Guide introduces various solutions utilizing TDK's advanced low-ESL components, the "YFF Series" 3-terminal feed-through filter.

For electronic device design, it is important to allow necessary signals to pass while to block unwanted signals (noise). Some pattern designs of a printed circuit board (PCB) can be influenced by ESD (electrostatic discharge). By visualizing the behavior of ESD intruding into the PCB, we can confirm the effectiveness of ESD countermeasures for the PCB design. In this article, we introduce effective GND pattern designs and the use of ESD protection components to enhance ESD robustness.
