Here are some additional details about this type of battery holder:

Battery Compatibility: CR2032 refers to the specific type of coin cell battery that this holder is designed for. It is a 3-volt lithium battery with a diameter of 20mm and a thickness of 3.2mm.

Horizontal Orientation: The horizontal orientation means that the CR2032 battery is positioned parallel to the surface of the PCB. This design is often used in applications where a flat or low-profile configuration is preferred.

Surface Mount Technology (SMT): The SMT feature indicates that the battery holder is designed for surface mounting directly onto the surface of the PCB. SMT eliminates the need for through-hole components and allows for automated assembly during the manufacturing process.

Case Design: The holder typically consists of a plastic or metal case with contacts or terminals that establish electrical connections with the positive and negative terminals of the CR2032 battery. The case is designed to securely hold the battery in place.

Polarity: As with any battery holder, it is crucial to observe the correct polarity when inserting the CR2032 battery into the holder. The positive and negative terminals on the battery should align with the corresponding contacts in the holder.

Space Efficiency: The horizontal orientation and surface-mount design contribute to space efficiency, making this type of battery holder suitable for compact electronic devices where board space is limited.
