This invention proposes an new type of inductor core unit for an inductor in order to achieve a longer operating period of the inductor with low sound emission while tolerating temperature fluctuations. The patent is active in Germany and France. It has counterparts in the U.S., China, Korea and Taiwan.
The invention discloses a printed circuit board (PCB) that suppress vibration or noise caused by connected electronic component such as ceramic capacitors, ferrite magnet coils.
This invention implements the application of a plug-type connector on a PCB but soldered horizontally. It is space-saving and may improve PCBs in general.
