We see from your search that you're looking for information on the term "Leakage current",
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".
Earlier in the week,
we featured the news release White LED driver cuts down on flicker from
Advanced Analogic Technologies: "By driving up to 10 white LEDs in a serial string, the AAT1239-1 simplifies the use of larger LCD panels in a wide array of battery-powered portable devices".
In January 2008, we covered the news from Young Electronics Group
concerning its Medically approved 1000W PSUs
- take a look at Power supplies are approved for medical uses
which says: "Medically approved 1000W power supplies are initially available with 5, 12 or 24V outputs".
Take a look also at the news release from AVX, Varistors protect CANs from ESD,
as well as External power adapters work worldwide from Emerson Network Power - Embedded Power,
and Single-output switchers add medical options from Lambda.
