Operating Temperature

The operating temperature is the range of ambient temperature within which a power supply, or any other electrical equipment, operate in. This ranges from a minimum operating temperature, to a peak or maximum operating temperature, outside which, the power supply may fail.

-40°C~125°C

Packaging

Semiconductor package is a carrier / shell used to contain and cover one or more semiconductor components or integrated circuits. The material of the shell can be metal, plastic, glass or ceramic.

Average Current

Ambient Temperature Range High

This varies from person to person, but it is somewhere between 68 and 77 degrees F on average. The temperature setting that is comfortable for an individual may fluctuate with humidity and outside temperature as well. The temperature of an air conditioned room can also be considered ambient temperature.

Radiation Hardening

Radiation hardening is the process of making electronic components and circuits resistant to damage or malfunction caused by high levels of ionizing radiation, especially for environments in outer space (especially beyond the low Earth orbit), around nuclear reactors and particle accelerators, or during nuclear accidents or nuclear warfare.

No
