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

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 "B25/85" 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 B25/75 in electronic components refers to the value of the beta (β) parameter of a transistor or a similar device, measured at two different temperatures, specifically 25°C and 75°C. It indicates the current gain of the transistor in the active region of operation at these specified temperatures. This parameter is important for determining the performance of the device under varying thermal conditions and is often used in designing circuits that require stable amplification characteristics. B25/75 helps engineers predict how the current gain may change with temperature, influencing the choice of components for specific applications.

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