During testing at KEMET, higher voltage devices are submerged in an insulating fluid to ensure testing
measures the actual voltage capability of the dielectric itself.
S-PARAMETER
S-Parameter (scattering matrix) is a tool that quantifies how RF energy propagates through a multi-port
network. S-Parameters can be used to describe a very complicated network as a simple “black box”.
RF engineers uses S-Parameter as a primary quantity to design RF circuits. The quantities describe how
much RF energy is injected into the network versus:
1. How much energy actually gets through
2. How much energy is absorbed, and
3. How much energy is reflected back to the source.
Here is an analogy using light through a lens:
Here is a visual for S-Parameter data in an electrical circuit:
KEMET will offer S-Parameter data at www.kemet.com/rf. Care should be taken when making calculations
on the provided data, as many factors in individual designs can impact the true S-Parameter as measured
in the final application. These factors include, but are not limited to:
Some electrical
network: capacitor,
filter, amplifier etc.
