MLCC powers efficient xEV resonant circuits

Samsung Electro-Mechanics’ CL32C333JIV1PN# high-voltage MLCC is designed for use in CLLC resonant converters targeting xEV applications such as BEVs and PHEVs. The capacitor provides 33 nF at 1000 V in a compact 1210 (3.2×2.5 mm) package, leveraging a C0G dielectric for high stability.

Maintaining capacitance across –55°C to +125°C with minimal sensitivity to temperature and bias, the device is well suited for high-frequency resonant tanks where electrical consistency directly impacts efficiency and control margin. The surface-mount capacitor enables power electronics designers to reduce component count and footprint in high-voltage CLLC resonant converter designs without compromising reliability.

Alongside the CL32C333JIV1PN#, the company offers two additional 1210-size C0G capacitors. The CL32C103JXV3PN# provides 10 nF at 1250 V, while the CL32C223JIV3PN# provides 22 nF at 1000 V. All three devices are manufactured using proprietary fine-particle ceramic and electrode materials, combined with precision stacking processes, and are optimized for EV charging systems.

The CL32C333JIV1PN#, CL32C103JXV3PN#, and CL32C223JIV3PN# are now in mass production.
