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.
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.
Learn how to simulate capacitors with your application's voltage, frequency, and temperature using KEMET's K-SIM. (Also known as KEMET SPICE.)
EMI Filter Modules come in a variety of form factors for many different industrial, medical, and alternative energy applications.
The last few years has seen a significant advancement in the design of high voltage X7R MLCC with higher capacitance that are resistant to arcing. The purpose of this paper is to explain how these work and their benefits. To do this we must first consider the different failure modes that can occur in X7R MLCC above 200V.
