2CR5 Lithium battery[FAQ+Video]: Equivalents, Datasheet, and 2CR5 vs CR123A

RATED voltage is the voltage on the nameplate - the "design point" for maximum power throughput and safe thermal operation.

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

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.

"Termination style" in electronic components refers to the method used to connect the component to a circuit board or other electronic devices. It determines how the component's leads or terminals are designed for soldering or mounting onto the circuit board. Common termination styles include through-hole, surface mount, and wire lead terminations.Through-hole components have leads that are inserted through holes in the circuit board and soldered on the other side. Surface mount components have flat terminals that are soldered directly onto the surface of the circuit board. Wire lead terminations involve attaching wires to the component for connection.The choice of termination style depends on factors such as the type of component, the manufacturing process, and the space available on the circuit board. Different termination styles offer various advantages in terms of ease of assembly, reliability, and space efficiency in electronic designs.

A battery is a device that stores chemical energy, and converts it to electricity. This is known as electrochemistry and the system that underpins a battery is called an electrochemical cell. A battery can be made up of one or several (like in Volta's original pile) electrochemical cells.

The most common lithium-ion cell is the 18650 (the numbers define the physical dimensions and shape as follows: 18mm in diameter, 65mm long and the 0 means it has a round cross-section) which is due to its widespread use in laptop battery packs.

In electronic components, "Capacity" typically refers to the maximum amount of electrical charge that a component can store. It is measured in units called farads (F). Capacitors are the most common components that have a capacity rating. The capacity of a capacitor determines how much energy it can store and release when connected in a circuit. Higher capacity capacitors can store more charge and are often used in applications requiring larger energy storage or filtering capabilities. It is important to select a capacitor with the appropriate capacity to ensure proper functioning of the circuit.

The "Discharge Rate" in electronic components refers to the rate at which a component can release stored energy or power. This parameter is particularly important in devices that use batteries or capacitors, as it determines how quickly these components can discharge their stored energy. A high discharge rate means that the component can release energy quickly, while a low discharge rate indicates a slower release of energy. Understanding the discharge rate of electronic components is crucial for designing circuits and systems that require specific power delivery characteristics.

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