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

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 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

HTS (Harmonized Tariff Schedule) codes are product classification codes between 8-1 digits. The first six digits are an HS code, and the countries of import assign the subsequent digits to provide additional classification. U.S. HTS codes are 1 digits and are administered by the U.S. International Trade Commission.

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.

Optoelectronic Device Type refers to the classification of electronic components that can both detect and emit light. These devices convert electrical signals into light or vice versa, making them essential for applications such as optical communication, sensing, and display technologies. Common types of optoelectronic devices include light-emitting diodes (LEDs), photodiodes, phototransistors, and laser diodes. Understanding the optoelectronic device type is crucial for selecting the appropriate component for a specific application based on factors such as wavelength, power output, and sensitivity.

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 photometry, luminous intensity is a measure of the wavelength-weighted power emitted by a light source in a particular direction per unit solid angle, based on the luminosity function, a standardized model of the sensitivity of the human eye.

The parameter "Wavelength - Peak" in electronic components refers to the specific wavelength at which the component's performance or characteristics reach their peak efficiency or effectiveness. This parameter is commonly used in devices such as LEDs, photodiodes, and laser diodes to indicate the optimal operating wavelength for maximum output or sensitivity. Understanding the peak wavelength is crucial for selecting the right component for a particular application, as it directly impacts the performance and functionality of the device. Manufacturers typically provide this information in datasheets to help engineers and designers make informed decisions when choosing electronic components for their projects.

Forward Current-Max is a parameter used to specify the maximum amount of current that an electronic component, such as a diode or LED, can safely handle when it is forward-biased. This parameter is crucial for determining the operating limits of the component to prevent damage or failure due to excessive current flow. Exceeding the specified Forward Current-Max can lead to overheating, degradation of the component, or even permanent damage. It is important to carefully consider this parameter when designing circuits to ensure the component operates within its safe limits.

Display Type in electronic components refers to the technology used to display information or visuals on a screen or panel. It describes the specific method or technology employed to present data, such as LCD (Liquid Crystal Display), OLED (Organic Light-Emitting Diode), LED (Light-Emitting Diode), or CRT (Cathode Ray Tube). Each display type has its own characteristics, including factors like resolution, color accuracy, viewing angles, power consumption, and response time. Choosing the right display type is crucial for determining the quality and performance of the visual output in electronic devices, such as smartphones, TVs, monitors, and digital signage.

The parameter "Digit/Alpha Size" in electronic components refers to the physical size of the digits or alphanumeric characters displayed on the component. It is typically measured in millimeters and indicates the height of the characters. This parameter is important for determining the readability and visibility of the displayed information on the component. A larger digit/alpha size would result in larger and more easily readable characters, while a smaller size may be suitable for applications where space is limited or where finer details are required. Manufacturers often provide specifications for digit/alpha size to help users select components that meet their specific display requirements.

In electronic components, the term "Common Pin" refers to a pin or terminal that is shared or connected to multiple circuits within the component. This pin serves as a reference point for signals or power supply connections. The Common Pin is often used to establish a common ground or voltage reference for the component, ensuring proper functionality and signal integrity. By connecting multiple circuits to a single Common Pin, designers can simplify the overall circuit layout and improve the efficiency of the component.

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