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.

Lead length refers to the distance from the body of an electronic component to the end of its leads or terminals. It is an important specification in component design and packaging, as it affects the ease of soldering, the overall fit within a circuit board, and the electrical performance. Longer leads can facilitate easier connections but may also introduce increased resistance or inductance in high-frequency applications. Proper lead length is crucial for ensuring reliable connections and optimal performance in electronic circuits.

Tolerance is the percentage of error in the resistor's resistance, or how much more or less you can expect a resistor's actual measured resistance to be from its stated resistance. A gold tolerance band is 5% tolerance, silver is 10%, and no band at all would mean a 20% tolerance.

The parameter "Resistance in Ω @ 25°C" in electronic components refers to the resistance value of the component measured in ohms at a temperature of 25 degrees Celsius. Resistance is a fundamental property of electronic components that determines how much they impede the flow of electric current. The resistance value at 25°C is often provided as a reference point because it is a standard temperature for many electronic applications. This parameter helps engineers and designers understand how the component will behave in a circuit and allows for accurate calculations of current flow and voltage drop.

The parameter "B25/85" in electronic components refers to the temperature coefficient of resistance. It indicates how the resistance of the component changes with temperature. Specifically, "B25" refers to the resistance value at 25 degrees Celsius, while "85" refers to the resistance value at 85 degrees Celsius. This parameter is important for understanding how the component will perform under different temperature conditions and is commonly used in the design and specification of electronic circuits.

The parameter "B25/50" in electronic components typically refers to the temperature coefficient of resistance. It indicates how the resistance of the component changes with temperature. The "B" value represents the temperature range over which the resistance is being measured, with 25/50 indicating a range from 25 to 50 degrees Celsius. A lower B value indicates a more stable resistance over temperature changes, while a higher B value means the resistance will vary more with temperature. This parameter is important for ensuring the proper functioning and reliability of electronic circuits in different temperature environments.
