New high-voltage MLCC benefits EV OBCs

Samsung Electro-Mechanics launches a high-performance CLLC-resonant MLCC that offers 22nF at 1000V. Providing the optimal solution for the OBCs of EVs, mass production of the innovative new CL32C223JIV1PN# is already underway, with samples available upon request.

Due to the electrification and high functionality of modern automobiles, the number of MLCCs mounted in a single vehicle is rising rapidly. Trends influencing specific MLCC characteristics include ongoing demands for miniaturisation, high voltage, stability and higher capacitance.

The company answers these demands with the development of its new device, an advanced product that comes in a compact 1210 (3.2mm x 2.5mm) form factor. With its 22nF capacitance and high rated voltage of 1000V, this high-capability MLCC is excellent for the OBCs needed by BEVs and PHEVs.

MLCCs specified for use in BEVs and PHEVs must be of quality construction and operate at high voltages to provide reliable charging of the traction battery by the OBC. The OBC converts AC to DC (adjusting DC output accordingly to suit the specific battery), while also providing PFC for shaping the input current to the power supply. Ceramic MLCCs (rather than plastic film capacitors) are the preferred choice for distributed capacitance because of their ability to withstand high temperatures.

The new Class 1 C0G (-55C to 125C) MLCC from the company fulfils the requirements of EV charging systems, proving OEMs and end users with a reliable and high-performance solution for the electrification era.
