We see from your search that you're looking for information on the term "Overloads",
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 Book outlines simple electronic design from
CRS, which we summarised at the time by saying "The author begins the book with an explanation of the working principles of semiconductor devices of various types".
A few weeks before,
we featured the news release Resistors stay stable at high temperatures from
IRC Wirewound and Film Technologies: "Standard and miniature high-power resistors withstand high temperatures and electrical overloads".
In April 2007, we covered the news from BI Technologies SMT
concerning its SMP series
- take a look at Surface mount power resistors handle up to 10W
which says: "With the highest power rating currently available, SMP series surface mount power resistors help designers of high power applications in confined spaces".
Take a look also at the news release from Tyco Electronics UK, Power resistors reduce costs,
as well as High-resolution graphics for harsh environments from Aitech Defense Systems,
and Accessories ease broadband microwave testing from Agilent Technologies Europe.
