Coin cell retainers are simple metal contacts that both electrically
connect coin cells and hold them in place, while taking up minimal
additional space on the PCB. They feature nickel-plating, and since most
coin cells have nickel shells this helps to prevent galvanic corrosion,
an electrochemical process that can damage dissimilar metals that are
in electrical contact. Our retainers are always designed with automation
in mind, and can be easily picked and placed, with both through hole
and surface mount retainers available for most coin cell sizes.
Combining the ease of automation with the low cost of MPD's retainers,
it is no wonder they are such a popular product.
Coin cell retainers take up little more room than bare coin cells.
