Summary:
Samsung has introduced a 1,000V 22nF multi-layer ceramic capacitor (MLCC), the CL32C223JIV1PN#, specifically designed for electric vehicle on-board chargers. This capacitor, constructed with a COG dielectric, operates reliably across a wide temperature range of -55 to +125°C with a tight tolerance of ±5%. With its compact surface mount packaging and high voltage capability, it is ideal for use in CLLC resonant power supply topologies.
Expansion:
Samsung's CL32C223JIV1PN# capacitor addresses the growing demand for high-quality components in the electric vehicle (EV) industry. As the market for EVs and plug-in hybrid electric vehicles (PHEVs) continues to expand, the need for reliable on-board chargers becomes paramount. These chargers must efficiently and safely charge the traction battery, requiring components that can withstand high voltages and temperature extremes.
The use of multi-layer ceramic capacitors, such as the CL32C223JIV1PN#, offers several advantages over traditional plastic film capacitors. MLCCs provide distributed capacitance and are capable of withstanding high temperatures, making them well-suited for demanding automotive applications. Additionally, their compact size and surface mount packaging enable efficient integration into compact PCB designs, essential for modern vehicle electronics.
The CL32C223JIV1PN# capacitor is particularly suitable for CLLC resonant power supply topologies, such as the CLLC converter described in Infineon's application note. The CLLC converter offers galvanic isolation and bidirectional operation, allowing for efficient power conversion in both step-up and step-down configurations. This versatility makes it an attractive solution for EV charging systems, where efficiency and reliability are paramount.
Overall, Samsung's CL32C223JIV1PN# capacitor represents a significant advancement in capacitor technology for electric vehicle applications. Its high voltage rating, temperature stability, and compact form factor make it an excellent choice for on-board chargers, contributing to the continued growth and adoption of electric vehicles worldwide.
