Coin Cell Retainers

ASTORIA, N.Y. - A new series of insulated low profile Coin Cell Retainers, suited for high density PCB packaging is the latest Keystone Electronics Corp's innovation for surface and thru hole mount battery retainers.

The unique, patent-pending design protects the battery from shorting if inserted incorrectly. These new retainers also allow the user to stack two 20mm cells on top of each other to achieve 6 volts of power from the same board footprint or for single cell 3-volt applications. The retainers are rugged yet lightweight, with clearly marked polarity, and are designed for both lead free solder and traditional reflow processes. The solder tails located outside the insulating material, support visual inspection systems.

6 volt power can be achieved using Catalog No. 3020 (SMT) or Catalog No. 3021 (THM) for (2) 2016 size coin cells, or Catalog No. 3022 (SMT) or Catalog No. 3023 (THM) for (2) 2020 or (2) 2025 size coin cells. The new retainers are available in bulk or on tape and reel.
