Mercury Magnetics also supports commercial and industrial customers with custom magnetics, power assemblies, and complete products built for demanding applications. From prototype development through production manufacturing, we provide U.S.-based support for customers who need custom transformers, PCB-based power assemblies, potted products, and dependable build-to-print manufacturing.
Some customers come to Mercury for early engineering collaboration and prototype support. Others already have a defined design and need a capable domestic manufacturing partner or second source. Mercury supports both.
