World’s Smallest High Voltage Ceramic Capacitors with Internal Arc Protection

kemetKEMET has announced the world’s smallest high voltage surface mount multilayer ceramic capacitors (MLCCs) with internal arc protection. The EIA 0603 case size has been added to KEMET’s High Voltage ArcShield product portfolio with voltage ratings up to 1,000 volts.

High voltage capacitors are typically limited by size due to arcing concerns. KEMET’s patented ArcShield technology is designed to suppress arc-over events, while allowing for the smallest available footprint and highest capacitance values in the industry.

“ArcShield is unique in that it provides permanent internal protection that prevents arcing in both coated and uncoated printed circuit board assemblies,” said Dr. John Bultitude, KEMET Vice President and Technical Fellow. “Most competitive technologies cannot prevent arcing within the capacitors’ voltage rating and require an external coating, which can be damaged during handling. KEMET’s patented ArcShield technology prevents arcing without the need of a surface coating. It also allows for the realization of smaller case size devices with exceptional lightning strike performance.”

A Dash of Maxwell’s: A Maxwell’s Equations Primer – Part Two

Maxwell’s Equations are eloquently simple yet excruciatingly complex. Their first statement by James Clerk Maxwell in 1864 heralded the beginning of the age of radio and, one could argue, the age of modern electronics.

KEMET High Voltage MLCCs are utilized in a variety of applications including high voltage coupling, DC blocking, snubber circuits in power supplies and high voltage noise reduction circuits. Available with flexible termination technology, ArcShield is offered in both commercial and automotive grades.
