We see from your search that you're looking for information on the term "EMI filtering",
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 Compact protectors cover ESD and EMI from
STMicroelectronics, which we summarised at the time by saying "Both devices meet IEC61000-4-2 level 4 for ESD protection and feature low line-to-earth capacitance of 30pF to preserve high-speed signal integrity".
A couple of weeks before,
we featured the news release Power supplies are approved for medical uses from
Young Electronics Group: "Medically approved 1000W power supplies are initially available with 5, 12 or 24V outputs".
In January 2008, we covered the news from Syfer Technology
concerning its Syfer discoidal multilayer ceramic capacitors
- take a look at Ceramic capacitors suit EMI filtering
which says: "Syfer's discoidal multilayer ceramic capacitors can be installed directly into filters, onto bulkheads, hybrid circuits or onto printed circuit boards".
Take a look also at the news release from Emerson Network Power - Embedded Power, Adapters are made for charging portable CE devices,
as well as Range cuts the cost of inductor-capacitor filters from California Micro Devices,
and Multifunction IC cleans up card interfaces from STMicroelectronics.
