"Surrounding" – the ambient temperature is the temperature of the air that surrounds the fixture in the room. Temperature surrounding a lamp or luminaire. A critical criterion for fixture selection especially in extreme temperature environments.
Refers to the temperature of the air immediately surrounding the fuse and is not to be confused with "room temperature." The fuse ambient temperature is appreciably higher in many cases, because it is enclosed (as in a panel mount fuseholder) or mounted near other heat producing components, such as resistors, transformers, etc.
According to MIL-STD-810E: The test unit shall be surrounded by an envelope of air, except at necessary support points. The gradient throughout this envelope shall be within 2Â°C of the test temperature and shall not exceed 1Â°C per meter.
The temperature surrounding the animal: under caging conditions may refer to the temperature in the microenvironment inside the cage as opposed to temperature outside the cage in the room or enclosure.
The temperature of the environment the inductor will be operating in. Typically this is specified as a temperature range and the maximum specified ambient temperature is used in conjunction with the temperature rise to determine the maximum current rating of the component.
The temperature of still air immediately surrounding a component or circuit. A typical method to measure ambient temperature is to record the temperature that is approximately 1/2 inch from the body of the component or circuit.
