Even very small amounts of water vapor inside an electrical housing or system can compromise the performance and reliability of the encapsulated electrical or optical components e.g. semiconductor chips. This is why internal moisture levels must be kept low enough to even avoid condensation, as its...
Depending on temperature, air can hold a fixed amount of water vapor; relative humidity is the ratio of actual vapor in the air to this fixed amount. For example, at a temperature of 68 degrees Fahrenheit (20 degrees Celsius), one cubic meter (35 cubic feet) of air can hold about 18 ...
