Terminal Finish refers to the surface treatment applied to the terminals or leads of electronic components to enhance their performance and longevity. It can improve solderability, corrosion resistance, and overall reliability of the connection in electronic assemblies. Common finishes include nickel, gold, and tin, each possessing distinct properties suitable for various applications. The choice of terminal finish can significantly impact the durability and effectiveness of electronic devices.

The Maximum Operating Temperature is the maximum body temperature at which the thermistor is designed to operate for extended periods of time with acceptable stability of its electrical characteristics.

The "Min Operating Temperature" parameter in electronic components refers to the lowest temperature at which the component is designed to operate effectively and reliably. This parameter is crucial for ensuring the proper functioning and longevity of the component, as operating below this temperature may lead to performance issues or even damage. Manufacturers specify the minimum operating temperature to provide guidance to users on the environmental conditions in which the component can safely operate. It is important to adhere to this parameter to prevent malfunctions and ensure the overall reliability of the electronic system.

The voltage level by which an electrical system is designated and to which certain operating characteristics of the system are related.

The distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals.

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 which flows upon application of forward voltage.

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.

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.

The parameter "Viewing Area (height)" in electronic components refers to the vertical dimension of the display or viewing area of a device, typically measured in millimeters or inches. It indicates the height of the visible screen space where information or images can be displayed. This parameter is important for determining the size and aspect ratio of the display, as well as for understanding the overall dimensions of the electronic component. Manufacturers often provide this specification to help users assess the suitability of the device for their intended application based on the available viewing area.

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

Lead Free is a term used to describe electronic components that do not contain lead as part of their composition. Lead is a toxic material that can have harmful effects on human health and the environment, so the electronics industry has been moving towards lead-free components to reduce these risks. Lead-free components are typically made using alternative materials such as silver, copper, and tin. Manufacturers must comply with regulations such as the Restriction of Hazardous Substances (RoHS) directive to ensure that their products are lead-free and environmentally friendly.
