SLC capacitors claim high dielectric constant

AVX Corp. has expanded its family of proprietary high k, intergranular barrier layer dielectric systems with the introduction of the Ultra Maxi series.

These single-layer ceramic (SLC) capacitors claim a record high dielectric constant at 60,000 with X7R characteristics. Similar to AVX's Maxi and Maxi+ product offerings, the Ultra Maxi SLC capacitors feature X7R characteristics and a dielectric constant of 60,000, which is double the previous industry high for Grain Boundary Barrier Layer (GBBL) formulations.

Available in voltage ratings of 6.3-, 16- and 25Vdc, the Ultra Maxi series is also said to set a standard for circuit miniaturization. "On average, the required board mounting area will be reduced by approximately two-thirds when compared to an equivalent capacitance value in our Maxi+ series," said Larry Eisenberger, AVX product marketing manager, in a statement.

The Ultra Maxi devices are RoHS compliant and Pb-free. Applications include broadband bypass and optical networking.

Delivery is four to six weeks. Samples and custom configurations are available on request.
