Spang Engineered Solutions works with you to solve even the most complex inductor problems.

Design & Analysis
We excel in solving challenges with new designs that have difficult-to-achieve targets, as well as improving existing designs that fall short of their targets. Our advanced design tools enable us to quickly prepare and present multiple inductor solutions with detailed output results. This speed allows our customers to select the best option for their system.

Prototyping
With immediate access to a wide variety of core materials and 3D printing of custom bobbins, we’re able to rapidly provide prototypes for our customers. Along with winding in the United States and China, this allows us to shorten your design cycle via a reduction in time spent waiting for prototypes to be built.

Testing
An in-house, custom-built test bed allows for immediate and rigorous testing of prototypes or customer-supplied inductors at application conditions. Temperature rise, losses, inductance swing and waveforms can be closely analyzed for a very wide range of input power levels, duty cycles and wave shapes.

Manufacturing
In collaboration with our other divisions, we can combine global manufacturing operations and supply-chain management to provide custom-built inductors at the quantity and timing our customers need. Winding and assembly can be done in the United States or China with toroids or shapes of any size.

Compliance & Certifications

UL Insulation Systems
At Spang Engineered Solutions, quality isn’t optional—it’s engineered in. Our products are built to meet rigorous industry standards, including compliance with UL-certified Electrical Insulation Systems under File Number E68030. From materials to manufacturing, we ensure every component delivers reliable, tested performance you can trust.
