Micrometals Custom E Cores Solve Challenging Power Conversion Applications

February 01, 2020 by Micrometals

One significant advantage to Micrometal’s E Cores is their distributed gap materials, which do not require any gapping to improve saturation like ferrite cores.

Micrometals, a leader in high-performance core solutions for power applications, continues to expand their prototyping and custom core capabilities with the expansion of new E Core variations available.

Micrometals E Cores are renowned for their performance and quality by delivering exceptional part-to-part consistency.  With over 20 industry-standard E Core sizes, from 12.7mm to 210mm, in both Iron and Alloy materials, Micrometals leads the industry in COTS shapes and materials.  



One significant advantage to Micrometal’s E Cores is its distributed gap materials, which do not require any gapping to improve saturation like ferrite cores. 

The expanded prototyping and customization capabilities allow Micrometals to customize their standard E Cores by shaping the outer legs or center post to improve the usability for customers.  This customization permits the use of pre-wound coils for higher winding density compared to traditionally square-shaped E Cores. Further, these custom E Cores deliver superior performance compared to similarly shaped cores that are custom tooled.

Jim Cox, Micrometals President commented “For decades, our customers have trusted Micrometals cores to deliver exceptional reliability, consistency, and performance.  With these expanded customization capabilities we deliver that same performance and consistency, but with more application friendly features that exceed our customer’s expectations in terms of performance and functionality.  Customer is also thrilled that they can get these as prototypes or production parts without any tooling costs, allowing them to test multiple designs without a large investment.” 

The full offering of Micrometals standard E Cores has been incorporated into the Micrometals Online Inductor Design Tool, for facilitating material selection and design optimization.
