The Ultra Maxi Series is the latest addition to the AVX family of proprietary high k, inter-
granular barrier layer dielectric systems. This series is similar to our Maxi and Maxi+
product offerings, but with the notable difference that the dielectric constant has been
increased to 60,000 – double the previous high for our industry leading GBBL
formulations.
These new Single Layer Ceramic Capacitors – available in voltage ratings of 6.3, 16 and
25 VDC – set a new 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. The Ultra Maxi Series offers an ideal solu-
tion for broadband bypass applications where high performance and the smallest foot-
print are the primary considerations.
The Ultra Maxi Series is RoHS compliant – as are all AVX SLC products. Terminations
(Au over Ti/W) provide an excellent wire bonding surface and are compatible with
conductive epoxy or Au/Sn eutectic solder attach.
Samples and custom configurations are available on request.
