We see from your search that you're looking for information on the term "EMI suppression",
and we have a large number of manufacturers' news releases and technical articles here on Electronicstalk which will be of interest.
Let me be your guide.
Start with
the news release Capacitors suppress electromagnetic interference from
Mouser Electronics, which we summarised at the time by saying "Evox Rifa's PHE840M EMI suppression capacitors are made with self-healing metalised polypropylene".
A couple of weeks before,
we featured the news release Assemblies maximise PCB real estate from
Molex UK: "Sealed SFP Assemblies are designed to maximise valuable PCB real estate, while providing an environmentally-sound interface".
In November 2007, we covered the news from Acal Components
concerning its B32021 to B32026 EMI suppression capacitors
- take a look at EMI suppression capacitors protect appliances
which says: "Acal Technology's Y2 EMI suppression capacitors are designed for operation in equipment that is continuously connected to single-phase power grids".
Take a look also at the news release from Murata Electronics (UK), EMI suppressors fit in small footprints,
as well as Online tool speeds component choices from Acal Technology,
and Connector modules for Power over Ethernet systems from Molex UK.
