KEMET’s HiQ- CBR series ceramics are a perfect t for higher
frequencies. Our CBR series MLCCs have a C0G dielectric,
which is an ultra-stable dielectric. The materials are chosen,
and the design is optimized, so the capacitors characteristics
are well suited to the higher frequencies. These capacitors have
a frequency range up to 50 GHz and are designed to have the
lowest possible ESR. This allows for minimal power loss at RF
frequencies. CBR Series devices are suitable for many circuit
applications including RF power ampliers, mixers, oscillators,
low noise ampliers, lter networks, antenna tuning, timing cir-
cuits, delay lines, and MRI imaging coils.
HIGH FREQUENCY PARTS?
There are many KEMET products that will contribute to the ad-
vancement of 5G technologies. I talked about the usage of high
frequency bands. This enables more concentrated, faster data
relaying.
We can see the use of 4G in cars today with GPS, in-car WiFi,
and connectivity to multiple devices. Some of the newer models
even provide a tra󰀩c light service using the 4G LTE. When the
vehicle approaches a connected tra󰀩c light, the driver sees a
display of how many seconds until the light changes green. I’m
not sure if this good or bad. I have many friends that are
aggressive drivers and have no patience when the light turns
green. Imagine if those aggressive drivers get to know how long
until the light turns green!
When 3G and 4G networks were developed, the developers
only had consumer voice and data in mind. Machine-to-machine
communications are only recently becoming prominent. There-
fore, 5G is being developed with machine-to-machine interface
in mind, so there will be more connected devices and vehicles.
LET’S TALK AUTOMOTIVE
The gaming industry will experience an interesting change!
The industry will move away from consoles, to a cloud-based
subscription service, o󰀨ering more exibility for the users. This
is because they will be able to stream the game to any device,
anywhere. Use of virtual reality for gaming is already signicant.
According to CNBC, Disney has partnered with Lenovo to create
an augmented reality (AR) “Star Wars” game, which users play
via their phone, a headset, and a lightsaber.
There will be a huge demand for parts in the automotive sector
as vehicles become more automated. This means we would
need more radio frequency (RF) and high frequency compo-
nents, as well as sensors and magnetics for noise reduction.
We also need to think of ways to load more power and memory
capabilities into a smaller package. Higher capacitance, voltage
(CV) parts, lower ESR/ESL, lower loss magnetics, high tempera-
ture components will all play a signicant role within KEMET.
HOW WILL 5G IMPACT KEMET?
KEMET also o󰀨ers a very unique product called the Flex
Suppressor®. They are available in the GHz band, which makes
them suitable for 5G applications. The Flex Suppressor is a
polymer-based exible sheet, blended with micron-sized
magnetic powders dispersed throughout the material.
There is virtually no limitation on where it can be used. You can
easily cut them into di󰀨erent shapes, so they can be used in
portable equipment. The picture below will give you an idea of
di󰀨erent application areas for KEMET’s Flex Suppressor.
