Common Mode Choke Design and Material Selection Presentation:
Wednesday, January 19, 2022 at 11:00 am U.S. EST
The common mode choke is a critical component in electromagnetic interference filtering. The magnetic material selected is commonly overlooked and is often not evaluated against application requirements. This 30-minute Webinar investigates the relationship between magnetic material properties and filtering performance. Multiple materials and winding configurations were tested across frequency and temperature. Test results are provided, analyzed, and compared with material property curves. The results provide a deeper understanding of magnetic materials and how they enable component optimization. To register, click here.
The next membership meeting will be face-to-face at Pinckney Hall on January 6th (yes, this Thursday) at 7 PM. Bob Heil will be the guest speaker. Hopefully, that will take up most of our time together.
