The "Mounting Type" in electronic components refers to the method used to attach or connect a component to a circuit board or other substrate, such as through-hole, surface-mount, or panel mount.

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

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, the "Series" refers to a group of products that share similar characteristics, designs, or functionalities, often produced by the same manufacturer. These components within a series typically have common specifications but may vary in terms of voltage, power, or packaging to meet different application needs. The series name helps identify and differentiate between various product lines within a manufacturer's catalog.

Parts can have many statuses as they progress through the configuration, analysis, review, and approval stages.

Moisture Sensitivity Level (MSL) is a standardized rating that indicates the susceptibility of electronic components, particularly semiconductors, to moisture-induced damage during storage and the soldering process, defining the allowable exposure time to ambient conditions before they require special handling or baking to prevent failures

Voltage - Supply refers to the range of voltage levels that an electronic component or circuit is designed to operate with. It indicates the minimum and maximum supply voltage that can be applied for the device to function properly. Providing supply voltages outside this range can lead to malfunction, damage, or reduced performance. This parameter is critical for ensuring compatibility between different components in a circuit.

The "Base Part Number" (BPN) in electronic components serves a similar purpose to the "Base Product Number." It refers to the primary identifier for a component that captures the essential characteristics shared by a group of similar components. The BPN provides a fundamental way to reference a family or series of components without specifying all the variations and specific details.

The parameter "Circuit" in electronic components refers to the interconnected arrangement of various electronic elements such as resistors, capacitors, inductors, and active devices like transistors. It defines the path through which electric current flows and establishes the operational behavior of the components within that system. Circuits can be classified as analog or digital, depending on the type of signals they handle, and can vary in complexity from simple series or parallel configurations to intricate designs used in advanced applications.

A voltage source is a two-terminal device which can maintain a fixed voltage. An ideal voltage source can maintain the fixed voltage independent of the load resistance or the output current. However, a real-world voltage source cannot supply unlimited current. A voltage source is the dual of a current source.

The term "Independent Circuits" in electronic components refers to the ability of a device to function as a separate and self-contained circuit within a larger system. In the context of electronic components, having independent circuits means that each circuit can operate autonomously without being directly affected by other circuits in the system. This feature allows for better isolation, control, and troubleshooting of individual circuits within a complex electronic system. Independent circuits are commonly found in devices such as integrated circuits, where multiple functional blocks are designed to operate independently to perform specific tasks efficiently. Overall, the presence of independent circuits in electronic components enhances the reliability, flexibility, and performance of the system as a whole.

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