Expert support for custom inductors and other challenging magnetics.
When you have a difficult inductance target or are scrambling to meet a deadline, Spang Engineered Solutions can take the problem of inductor design off your hands and help complete your project successfully.
Custom Parts
Our speciality is high power inductive components. Using advanced design tools, our electrical design engineers prepare multiple alternatives for initial review. By presenting options side-by-side, our design team can help you clearly see the tradeoffs that are available. This helps to find the most optimal solution. It also helps to show quickly if we are a good fit for your business.
Sizes
Experience with large chokes makes us unique, but our engineers can design for any power level. Whether you need 5µH at 2A or 50µH at 700A, we can offer options and get to a solution fast.
Other Components
We do more than design and build inductors. We meet tough challenges with all types of magnetics and magnetic assemblies.
- Filter Inductors
- Potted Assemblies for Strength
- Small Power Inductors
- Thermally Conductive Assemblies
- Power Transformers
- PCB-Mounted Assemblies
- Pulse and Current Transformers
- Brackets and Fixtures
- Air Coil Inductors
- Packaged Modules

Versatility
Spang Engineered Solutions can review an existing magnetic design to help find improvements or make necessary changes. Or we can help lay out the initial requirements for a brand new magnetic. Our scope includes a wide range of core materials and custom bobbin types, plus the potting materials and mounting fixtures best suited for each application. Each project is unique, and we adapt our approach each time to give our customer just the support desired, and arrive at just the solution needed.

Toroid Winding
