Designed to meet the growing demand for high rated voltage solutions within the electric vehicle (EV) industry, these 1812 inch X7R MLCCs offer 2.2nF~470nF capacitance and, most notably, rated voltage up to 2000Vdc.
With the development of EVs there is now a trend towards the application of higher voltages to a growing list of power electronic components. In motion, the vehicle’s charging and distribution system supplies energy to the electric drive system, motors and other sub-systems. Initial generations of EVs connected these sub-systems using 400V power rails. Today the move is towards 800V platforms, not just to take advantage of fast-charging technologies but also the greater efficiency of drivetrains at high torque or speed (from higher applied voltage).
There are a number of obvious implications of this shift for key electronic components such as on-board chargers (OBCs), motor drive inverters, DC-DC converters, wireless power transfer systems (WPTs), battery management systems (BMS), compressors and pumps. All require the support of MLCCs offering high rated voltage.
To carry a high voltage rating, MLCCs require a number of key engineering attributes and the latest solution from Samsung Electro-Mechanics sees higher bending strength in the already substantial 1812-inch (4.5×3.2mm) size by employing proprietary ceramics, micronizing materials, and the application of innovative soft termination technology.
These factors have been successfully combined to meet the high-voltage demands of the latest electronic components for EVs. As a point of note, the new MLCCs comply with AEC-Q200, the global standard for stress resistance that all passive electronic components must meet for use within the automotive industry.
Carrying the package codes CL43B222KJRRP#, CL43B224KHU6PJ# and CL43B474KEU6PJ#, mass production of these state-of-the-art MLCCs is already underway.
Suitable for use in operating temperatures up to 125°C, all of the new MLCCs from Samsung Electro-Mechanics offer RoHS and REACH compliance.
