Memory Protection Devices has invented another whole new category of coin cell battery holders called Minis, which drastically reduce the height of battery holders on PCBs. The first Mini being released is the BU2032SM-JJ-MINI-GCT, designed for use with CR2032 batteries. While other CR2032 holder solutions often rise almost 5 mm above the PCB, MPD's BU2032SM-JJ-MINI-GCT rises under 2 mm with an installed CR2032. This directly saves almost 3 mm in board height when compared to typical CR2032 battery holders available on the market.
Minis are built for reliability, with gold-flashed, nickel-plated phosphor bronze contacts that resist corrosion. The dual pressure contacts offer low electrical resistance and resistance to intermittent connections, while the recurved positive contacts provide extra retention on the coin cell battery. The lightweight LCP base piece of the holder is extremely strong, and can easily withstand temperatures of up to 280°C for modern, lead-free reflow soldering. Additionally, the LCP has excellent chemical resistance and can withstand repeated sterilizations by standard methods used in medical device assembly, including gamma and electron beam, ethylene oxide, and hot steam or hot air processes. The LCP used is also halogen-, PFOS-, and PFOA-free, as well as SVHC, REACH, RoHS, and WEEE compliant – meaning that Minis meet global environmental regulations.
