Insulated low profile Coin Cell Retainers, suited for high density PCB packaging. The unique, patent-pending design protects the battery from shorting if inserted incorrectly. These new holders allows the user to stack two 20mm cells on top of each other to achieve 6 volts of power from the same board footprint or use a single cell for 3 volt applications.

Retainers are rugged yet lightweight, with clearly marked polarity, designed for both lead free solder and traditional reflow processes. The solder tails are located outside the insulating material to support vision inspection system.

6 volt power can be achieved using Catalog # 3020 (SMT) or 3021 (THM) for (2) 2016 size coin cells, or Catalog # 3022 (SMT) or 3023 (THM) for (2) 2020 or (2) 2025 size coin cells. Retainers are available in bulk or on tape and reel.
