refers to the protective housing that encases an electronic component, providing mechanical support, electrical connections, and thermal management.

The DC Voltage ratings are the AC voltage values times 1.41 (usually rounded).

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.

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.

In electronic components, "tolerance" refers to the acceptable deviation or variation from the specified or ideal value of a particular parameter, such as resistance, capacitance, or voltage. It indicates the range within which the actual value of the component can fluctuate while still being considered acceptable for use in a circuit. Tolerance is typically expressed as a percentage or a specific value and is important for ensuring the accuracy and reliability of electronic devices. Components with tighter tolerances are more precise but may also be more expensive. It is crucial to consider tolerance when selecting components to ensure proper functionality and performance of the circuit.

Capacitance is a fundamental electrical property of electronic components that describes their ability to store electrical energy in the form of an electric field. It is measured in farads (F) and represents the ratio of the amount of electric charge stored on a component to the voltage across it. Capacitors are passive components that exhibit capacitance and are commonly used in electronic circuits for various purposes such as filtering, energy storage, timing, and coupling. Capacitance plays a crucial role in determining the behavior and performance of electronic systems by influencing factors like signal propagation, frequency response, and power consumption.

Lead Spacing (mm) refers to the distance between the centerlines of the leads (metal wires) of an electronic component, typically measured in millimeters. This parameter is important for determining how the component will fit onto a circuit board or into a socket. The lead spacing helps ensure proper alignment and spacing between components to prevent short circuits or other electrical issues. It is a critical specification to consider when designing or selecting electronic components for a circuit layout.

RoHS means “Restriction of Certain Hazardous Substances” in the “Hazardous Substances Directive” in electrical and electronic equipment.
