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 - Output Voltage
Output voltage is a crucial parameter in electronic components that refers to the voltage level produced by the component as a result of its operation. It represents the electrical potential difference between the output terminal of the component and a reference point, typically ground. The output voltage is a key factor in determining the performance and functionality of the component, as it dictates the level of voltage that will be delivered to the connected circuit or load. It is often specified in datasheets and technical specifications to ensure compatibility and proper functioning within a given system.
3V - Terminal Type
Terminal type or emulation specifies how your computer and the host computer to which you are connected exchange information.
BUTTON(+), FLAT(-) - Battery Chemistry

Lithium Manganese Dioxide - Outside Diameter
The outer diameter (OD) of a hollow circular pipe is the measurement of the outside edges of the pipe passing through its center.
24.5 mm - 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 24.5mm - 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.
1Ah - Discharge Rate
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.
200μA - Chemistry/Technology
The parameter "Chemistry/Technology" in electronic components refers to the specific materials and manufacturing processes used to create the component. It encompasses the chemical properties of materials such as semiconductors, dielectrics, and conductors, which influence performance characteristics like conductivity, thermal stability, and reliability. This parameter is critical for determining the suitability of components for various applications, including considerations like environmental impact, degradation over time, and compatibility with other materials. Understanding the chemistry and technology behind electronic components is essential for advancing performance and innovation in the field.

CR2477 Battery Safety
Although most CR2477 batteries do not contain mercury, cadmium, or other contaminants, they must be disposed of appropriately, just like any other battery.
LiR2477 batteries must be charged with chargers designed for them, or they could catch fire and perhaps explode.
Although CR/BR/LiR2477 batteries are not small and the risk of them being swallowed by a child or pet is negligible, keep them away from children and pets.
However, if they are eaten, contact your local emergency services for assistance; these batteries are not only difficult to swallow, but also difficult to vomit.
