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.

In electronic components, the parameter "Size / Dimension" refers to the physical dimensions of the component, such as its length, width, and height. These dimensions are crucial for determining how the component will fit into a circuit or system, as well as for ensuring compatibility with other components and the overall design requirements. The size of a component can also impact its performance characteristics, thermal properties, and overall functionality within a given application. Engineers and designers must carefully consider the size and dimensions of electronic components to ensure proper integration and functionality within their designs.

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

The parameter "Configuration" in electronic components refers to the specific arrangement or setup of the components within a circuit or system. It encompasses how individual elements are interconnected and their physical layout. Configuration can affect the functionality, performance, and efficiency of the electronic system, and may influence factors such as signal flow, impedance, and power distribution. Understanding the configuration is essential for design, troubleshooting, and optimizing electronic devices.

The "Max Current Rating" parameter in electronic components refers to the maximum amount of electrical current that the component can safely handle without being damaged. It is an important specification to consider when designing or selecting components for a circuit, as exceeding the maximum current rating can lead to overheating, malfunction, or even permanent damage to the component. The max current rating is typically provided in amperes (A) and is determined by the component's internal construction, materials used, and thermal characteristics. It is crucial to ensure that the current flowing through the component does not exceed this specified limit to maintain the component's reliability and longevity.

The parameter "Voltage - Forward (Vf) (Typ)" in electronic components refers to the typical forward voltage drop across the component when it is conducting current in the forward direction. It is a crucial characteristic of components like diodes and LEDs, indicating the minimum voltage required for the component to start conducting current. The forward voltage drop is typically specified as a typical value because it can vary slightly based on factors such as temperature and manufacturing tolerances. Designers use this parameter to ensure that the component operates within its specified voltage range and to calculate power dissipation in the component.

the angle at which a display can be viewed with acceptable visual performance.

Current - Test is a parameter in electronic components that refers to the maximum current that the component can handle during testing without being damaged. This parameter is crucial for determining the operational limits of the component and ensuring its reliability under specified conditions. It is typically specified in the component's datasheet and is important for designers and engineers to consider when designing circuits to prevent overloading the component. Testing the component at or below the specified "Current - Test" value helps ensure its proper functioning and longevity in the intended application.

In the context of electronic components, the parameter "Lens Style" typically refers to the design or shape of the lens used in optical components such as LEDs, photodiodes, or sensors. The lens style can affect the light output, beam angle, and overall performance of the component. Common lens styles include flat top, dome, narrow beam, wide beam, and diffused lenses. Choosing the appropriate lens style is important for achieving the desired light distribution and optical characteristics in electronic devices. Manufacturers often provide specifications on the lens style to help users select the most suitable component for their application.

Lumens/Watt @ Current - Test is a measurement used to evaluate the efficiency of light-emitting components, such as LEDs, under specific test conditions. It indicates the amount of luminous flux produced (in lumens) for every watt of electrical power consumed by the device at a given current level. This metric helps in assessing the brightness and energy efficiency of lighting solutions, allowing for better comparisons between different products and technologies. Higher values signify more efficient light sources that produce more light for less energy consumed.

The Color Rendering Index (CRI) is a measurement of how accurately a light source can render colors compared to natural light. It is a scale from 0 to 100, with higher values indicating better color rendering. A CRI value of 100 means the light source can accurately reproduce all colors. A high CRI is important in applications where color accuracy is crucial, such as in photography, art galleries, and retail settings. It helps ensure that colors appear true and vibrant under the light source.

the amount of voltage needed to get current to flow across a diode.

Lenses are classified by the curvature of the two optical surfaces. A lens is biconvex (or double convex, or just convex) if both surfaces are convex. If both surfaces have the same radius of curvature, the lens is equiconvex. A lens with two concave surfaces is biconcave (or just concave).

The Light Emitting Surface (LES) in electronic components refers to the specific area of a light-emitting device, such as an LED, that is responsible for emitting visible light. This surface can vary in size and shape depending on the design and application of the component. The characteristics of the LES, including its efficiency and uniformity, directly impact the overall performance and brightness of the light emitted. It plays a crucial role in applications where precise light distribution is required, such as in lighting fixtures, displays, and signaling devices.

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