Here are some key Features and Details about this Component:

Battery Compatibility: The holder is designed to accommodate a CR1220 coin cell battery. CR1220 batteries are 3-volt lithium coin cells with a diameter of 12mm and a thickness of 2.0mm.

SMD (Surface Mount Device): The SMD designation indicates that the battery holder is designed for surface mounting directly onto a printed circuit board (PCB). This is a common method of mounting electronic components during the manufacturing process, offering space efficiency and compatibility with automated assembly.

Button Battery Holder: The holder is specifically designed for button cell batteries, which have a distinctive coin-like shape. The term "button" refers to the shape of these batteries.

Pin Gold-Plated: The presence of gold-plated pins suggests that the electrical contacts or pins on the holder are coated with a layer of gold. Gold plating is often used for its corrosion resistance and good conductivity, ensuring reliable electrical connections.

Pin Configuration: The pins are the metal contacts that connect the battery holder to the PCB. The gold-plated pins help enhance the electrical conductivity and minimize issues related to oxidation or corrosion.

Polarity: As with any battery holder, it's crucial to observe the correct polarity when inserting the CR1220 battery into the holder. The positive and negative terminals on the battery should align with the corresponding contacts in the holder.
