Who We Are
We manufacture inductors and transformers for systems serving vital functions in the real world. Our role begins once a design is electrically sound and ready to be locked for production. We focus on making that design repeatable and stable over time.
We do not impose minimum order quantities (MOQs) and proudly support custom geometries and mixed production runs where other suppliers can't or won't. We hold tight process controls and solely release designs whose behavior we can predict across lots and volume.
Founded by educators, our approach is deliberate and exacting. We value clarity over speed, discipline over heroics. The result is magnetics that hold system stability.
More on who we are →Who We Serve
Our inductors are used inside power conversion, sensing, imaging, and control systems operating under continuous electrical and thermal load.
We support programs in aerospace, defense, industrial safety, and a wide range of commercial infrastructure hardware.
How We Work
Ampersand is structured for sustained production. Most of our work supports recurring needs with predictable schedules and consistent output.
We support both high-volume production and mixed builds involving lower volumes or non-standard form factors.
Each individual component is inspected and tracked, and we align documentation and delivery to your build cycle.
