Contact plating (finish) provides corrosion protection for base metals and optimizes the mechanical and electrical properties of the contact interfaces.

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, "tolerance" refers to the acceptable deviation or variation from the specified or ideal value of a particular parameter, such as resistance, capacitance, or voltage. It indicates the range within which the actual value of the component can fluctuate while still being considered acceptable for use in a circuit. Tolerance is typically expressed as a percentage or a specific value and is important for ensuring the accuracy and reliability of electronic devices. Components with tighter tolerances are more precise but may also be more expensive. It is crucial to consider tolerance when selecting components to ensure proper functionality and performance of the circuit.

Termination in electronic components refers to the practice of matching the impedance of a circuit to prevent signal reflections and ensure maximum power transfer. It involves the use of resistors or other components at the end of transmission lines or connections. Proper termination is crucial in high-frequency applications to maintain signal integrity and reduce noise.

The resistance-change factor per degree Celsius of temperature change is called the temperature coefficient of resistance. This factor is represented by the Greek lower-case letter “alpha” (α). A positive coefficient for a material means that its resistance increases with an increase in temperature.

Resistance is a fundamental property of electronic components that measures their opposition to the flow of electric current. It is denoted by the symbol "R" and is measured in ohms (Ω). Resistance is caused by the collisions of electrons with atoms in a material, which generates heat and reduces the flow of current. Components with higher resistance will impede the flow of current more than those with lower resistance. Resistance plays a crucial role in determining the behavior and functionality of electronic circuits, such as limiting current flow, voltage division, and controlling power dissipation.

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.

Parameter "Composition" in electronic components refers to the specific materials and substances used in the construction of the component. It encompasses the chemical and physical elements that make up the component, influencing its electrical, thermal, and mechanical properties. The composition can affect the performance, reliability, and durability of the component in various applications. Understanding the composition is essential for optimizing the design and functionality of electronic devices.

The "Power Rating" of an electronic component refers to the maximum amount of power that the component can handle or dissipate without being damaged. It is typically measured in watts and is an important specification to consider when designing or selecting components for a circuit. Exceeding the power rating of a component can lead to overheating, malfunction, or even permanent damage. It is crucial to ensure that the power rating of each component in a circuit is sufficient to handle the power levels expected during normal operation to maintain the reliability and longevity of the electronic system.

Case Code (Metric) in electronic components refers to a standardized system that specifies the dimensions of surface-mount devices (SMD) in millimeters, consisting of a four-digit number where the first two digits represent the width and the last two digits represent the height of the component, measured in tenths of a millimeter. The metric case codes are standardized by organizations such as the EIA and IEC, and are often compared to the Imperial code which uses inches, allowing for easier identification and selection of components across different regions and industries. This coding system is widely used in the design and manufacturing of electronic devices, particularly in applications requiring compact and efficient component layouts, and is essential for engineers and designers to ensure proper component selection and facilitate the assembly process in electronic manufacturing.

The term "Case Code (Imperial)" in electronic components refers to a standardized system used to specify the physical dimensions and package types of components, particularly capacitors and resistors. This code helps manufacturers and engineers identify the size and form factor of the component, ensuring compatibility with circuit designs and PCB layouts. In the context of electronic components, the Case Code (Imperial) typically follows a numerical format that indicates the length and width of the component in inches. For example, a Case Code of 1206 signifies a component that measures 0.12 inches by 0.06 inches. This coding system is essential for selecting the correct components for specific applications, as it provides a quick reference to the physical characteristics of the part, including its footprint and mounting style.

Radiation hardening is the process of making electronic components and circuits resistant to damage or malfunction caused by high levels of ionizing radiation, especially for environments in outer space (especially beyond the low Earth orbit), around nuclear reactors and particle accelerators, or during nuclear accidents or nuclear warfare.

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.
