The need for smaller case size, high voltage capacitors has driven the development of a new range of surface mountable, multi-layer ceramic capacitors (MLCC) for use in Automotive Applications. These X7R type capacitors, with 0603 and 0805 case sizes, have voltage ratings of 500, 630 and 1000VDC.
These X7R type capacitors, with 0603 and 0805 case sizes, have voltage ratings of 500, 630 and 1000VDC. They employ designs that prohibit arcing allowing higher capacitances to be realized in these smaller sizes. The development of this technology is reviewed and the challenges associated with smaller terminal to terminal separations are discussed.
The high density Silicon capacitors with multiple metal-insulator-metal (MIM) layer stacks in 3D structures are reaching today 250nF/mm2 in mass production and have been demonstrating densities of up to 1μF/mm2, confirming the target of more than 4μF/mm2 in the coming years.
100nF/mm2 (PICS3HV). 2. Stability over a large temperature range Most of the capacitors commercially available for use at 220°C show a significant change in capacitance above 150°C.
