The company’s latest series insulated, low-profile coin-cell retainers employ a patent-pending design that protects the battery from shorting if inserted incorrectly. The components allow users to stack two 20-mm 3V cells on top of each other to achieve 6V of power. They are rugged and lightweight with clearly marked polarity and support lead-free and traditional reflow processes. Additionally, solder tails are on the outside of the insulating material to support visual-inspection systems. KEYSTONE ELECTRONICS CORP. Astoria, NY. (800) 221-5510.
