|3012 Coin Cell Clip|
The 3012 Coin Cell Clip is small, easy to install, and use. The two small solder tabs are used to attach the clip to the PCB
The exposed clip is positive (+) and a user supplied pad on the PCB is negative (-).
An example of usage and required negative pad can be seen on the DipTrace 3D layout.
