High Voltage Compatible! C0G Characteristic Capacitor for Resonant Circuits that Supports Higher Output and Miniaturization of Automotive OBCs

On Board Chargers (OBCs) installed in electric vehicles are becoming increasingly powerful, with an output power of 22 kW. Even at higher power output levels, it is not acceptable to increase the size of the OBC itself, so compact design is required. Capacitors for the resonant circuit function are required to have high withstand voltage and low loss products that can withstand higher power densities than conventional products.
In order to meet this demand, TDK has released a new autograde C0G MLCC series with a rated voltage of 1250 V.

Product Development Utilizing TDK's Proprietary Pattern Coil Technology

TDK's proprietary pattern coil technology allows for precise and flexible adjustments to the thickness of copper traces based upon application requirements. This capability enables highly customizable coil designs that are not achievable with conventional copper coil technologies such as those created by etching.
The end-product lineup includes: wireless power transfer coils, RFID/NFC antennas for both communication and power, and EMI mesh screens. By applying pattern coil technology, it can be developed for a variety of end uses.
