- 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 20.0mm - 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.
225mAh - 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 - 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.

No - RoHS Status
RoHS means “Restriction of Certain Hazardous Substances” in the “Hazardous Substances Directive” in electrical and electronic equipment.
Non-RoHS Compliant - Lead Free
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.
