Wide-bandgap applications need DC Link and decoupling capacitors that can withstand 200°C, work at 1 MHz switching frequencies, and support up to 2,000 V. KEMET continues to move forward on developing the most advanced ceramic DC Link capacitor technology. Dr. John Bultitude presents the work his team has done to make ultra-stable, highly robust Ceramic DC Link Capacitors available in Leadless stacks.
Embedded capacitors enable thinner devices. At APEC 2017 KEMET previewed a new aluminum polymer technology that can be embedded directly into the silicon for a power converter.
Many applications require the use of RFI (Radio Frequency Interference ) X2 capacitors with high stability in harsh environmental conditions e.g. general-purpose applications in series to the mains (capacitive voltage dividers, energy meters) and automotive ones (battery chargers). KEMET released recently a new fully-approved RFI X2 metallized film series, suitable for both series and parallel- to-the-mains connection, designed for high capacitance stability in harsh conditions.
Understand why technical advances, changes in the tantalum supply chain, and new ore deposits make tantalum capacitors a substitute for many applications.
Wide bandgap semiconductors are driving the need for ceramic DC-Link capacitor solutions. At PEIM, KEMET presented work related to our BME C0G technology.
