High voltage MLCC for EV on-board chargers

High voltage MLCC for EV on-board chargers

By Nick Flaherty

Samsung Electro-Mechanics is launching a high-performance CLLC-resonant MLCC (multi-layer ceramic capacitor) for on-board chargers (OBCs).

The CL32C223JIV1PN MLCC offers 22nF at 1000V in a compact 1210 (3.2 x 2.5mm) form factor.

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

MLCCs specified for use in electric vehicles must be of quality construction and operate at high voltages to ensure 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 power factor correction (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 CL32C223JIV1PN# Class 1 C0G (-55 to 125°C) MLCC from Samsung Electro-Mechanics meets the full requirements of electric vehicle charging systems, proving OEMs and end users with a reliable and high-performance solution for the electrification era.

Mass production of the CL32C223JIV1PN MLCC is already underway, with samples available upon request.
