Coeur CST High-Current Interconnect System

Molex's Coeur CST interconnect system assures ease of mating and prevents potential damage to the socket contacts

Image of Molex's Coeur CST High-Current Interconnect System Molex's Coeur CST high-current interconnect system delivers up to 200.0 A of current through 3 diameter sizes (3.40 mm, 6.00 mm, and 8.00 mm) and offers a wide range of configurations, connecting PCBs, busbars, and cables. It is difficult to have perfect pin-to-socket alignment when mating two rigid PCBs or bus bars. A degree of float is needed in these situations to accommodate any misalignment there may be. Coeur CST high-current interconnect system provides up to 1.0 mm of float (industry-leading) in all three sizes. This diversity serves to assure ease of mating and also prevents potential damage to the socket contacts.

Dense electronic packaging demands ever lower profiles, minimal protrusions above mated PCBs or busbars, or both. Coeur CST high-current interconnect system offers a mated profile as low as approximately 5.00 mm in all three sizes. It can do so without the compromise of requiring large protrusions above or below the mated boards.

Power efficiency is critical to cost management in large power-consuming operations, such as data centers and similar applications. Coeur CST high-current interconnect system is designed with multiple contact beams per socket. This design serves to assure a solid electrical performance (low voltage drop).
