We see from your search that you're looking for information on the term "Capacitance",
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 Power switches protect USB connections from
Texas Instruments (April 2006-), which we summarised at the time by saying "Protects an input voltage supply against potential short-circuit conditions that may occur when using a USB connection".
The day before,
we featured the news release Capacitors stack up military reliability from
Kemet Electronics Corp: "SMPS stacked capacitors are an excellent choice for electrical applications, general purpose applications and high-frequency power supply circuits".
In February 2008, we covered the news from STMicroelectronics
concerning its EMIF01-1003M3 and EMIF02-1003M6
- take a look at Compact protectors cover ESD and EMI
which says: "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".
Take a look also at the news release from Tyco Electronics UK, IEC-inlet filters adopt slimline form,
as well as Supervisors sequence up to five power supplies from Maxim Integrated Products,
and Varistors protect data lines from AVX.
