RATED voltage is the voltage on the nameplate - the "design point" for maximum power throughput and safe thermal operation.
1.5V - Size / Dimension
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.
0.31Dia x 0.14 H 7.9mmx3.6mm - Part Status
Parts can have many statuses as they progress through the configuration, analysis, review, and approval stages.
Active - Moisture Sensitivity Level (MSL)
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
Not Applicable - Reach Compliance Code
Reach Compliance Code refers to a designation indicating that electronic components meet the requirements set by the Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) regulation in the European Union. It signifies that the manufacturer has assessed and managed the chemical substances within the components to ensure safety and environmental protection. This code is vital for compliance with regulations aimed at minimizing risks associated with hazardous substances in electronic products.
compliant - Termination Style
"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.
Requires Holder - Storage/Refrigeration Temperature
The parameter "Storage/Refrigeration Temperature" in electronic components refers to the recommended temperature range at which the components should be stored to maintain their integrity and functionality. This parameter indicates the temperature limits within which the components can be safely stored without risking damage or degradation. Storage temperature is crucial for preserving the performance and reliability of electronic components over time, especially for sensitive components such as integrated circuits and semiconductors. Refrigeration temperature may be specified for certain components that require lower temperatures to prevent degradation or prolong shelf life. It is important to adhere to the recommended storage/refrigeration temperature guidelines to ensure the longevity and proper functioning of electronic components.
50°F~77°F 10°C~25°C - Battery Chemistry
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.
Alkaline Manganese Dioxide - Battery Cell Size
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.
Coin 7.9mm - Capacity
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.
45mAh - Battery Type
Battery type refers to the specific chemistry and design of a battery that determines its characteristics, performance, and applications. Common battery types include alkaline, lithium-ion, nickel-metal hydride, and lead-acid, each with unique properties such as voltage, capacity, energy density, and discharge rates. The choice of battery type affects factors such as longevity, rechargeability, and suitability for various electronic devices and systems. Understanding battery type is crucial for selecting the appropriate power source for specific electronic components and applications.
PRIMARY - RoHS Status
RoHS means “Restriction of Certain Hazardous Substances” in the “Hazardous Substances Directive” in electrical and electronic equipment.
Non-RoHS Compliant
