Microchip SF200-28-28S-E-H

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.

The order of a filter also indicates the minimum number of reactive components that the filter will require. For example, a third-order filter requires at least three reactive components one capacitor and two inductors, two capacitors and one inductor, or in the case of an active filter, three capacitors.
