AVX Tantalum Chip Capacitors Deliver Higher CV Than X5R Dielectric Ceramic Devices

News

AVX Corporation has more than doubled the volumetric efficiency of its tantalum technology, enabling latest versions of its TACmicrochip capacitor to deliver 15µF/4V and 10µF/6V from a 0402 chip. The CV performance of these TLC series devices is even greater than ceramic MLCC devices using the X5R dielectric.

The design of the TACmicrochip capacitor series eliminates the need for molded plastic from the packaging that is required in traditional designs, allowing much greater capacitance to be squeezed into a given package. This has increased the volumetric efficiency from less than 15% to approaching 50%, making them applicable for a much wider range of uses.
Several series of TACmicrochip are available. High CV 15µF/4V, 10µF/6V TLC parts suit miniature application such as hearing aids, ultra-thin smart phones and tablet PCs. These devices are very stable; for example capacitance does not drop with applied DC voltage or AC ripple voltage.
