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.

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.

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.

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

Power - Max is a parameter that specifies the maximum amount of power that an electronic component can handle without being damaged. It is typically measured in watts and indicates the upper limit of power that can be safely supplied to the component. Exceeding the maximum power rating can lead to overheating, malfunction, or permanent damage to the component. It is important to consider the power-max rating when designing circuits or systems to ensure proper operation and longevity of the electronic components.

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 "B Value Tolerance" is a parameter used in electronic components, particularly in resistors and thermistors. It refers to the tolerance or variation in the B value of a component, which is a measure of how the resistance of the component changes with temperature. The B value is a constant that characterizes the temperature-resistance relationship of the component. A smaller B Value Tolerance indicates a more precise and consistent temperature-resistance behavior across different components of the same type. Manufacturers specify the B Value Tolerance to ensure that components meet certain performance standards and to help designers select components with the desired temperature characteristics for their applications.

The parameter "B25/100" in electronic components refers to the temperature coefficient of resistance. It indicates how the resistance of the component changes with temperature. Specifically, "B25/100" means that the resistance value is measured at 25 degrees Celsius and 100 degrees Celsius. The parameter helps designers and engineers understand how the component will perform under different temperature conditions, allowing them to select the appropriate component for their specific application. A lower temperature coefficient value indicates that the resistance of the component is more stable over a range of temperatures.

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