30mH 5A Nanocrystalline Core Common Mode Choke for Renewable Energy Systems
CMT2510BNA-303-5A-LF
Low-loss wideband choke designed for wind turbines, solar inverters, and green energy applications.
Nanocrystalline common mode chokes are well recognized for their superior impedance characteristics, wideband EMI suppression, and lower core losses compared with ferrite alternatives. With excellent thermal stability and compact size, they are widely used in power inverters, renewable energy systems, automotive electronics, industrial drives, and communication equipment. By offering reliable performance in both low-current precision circuits and high-current power stages, nanocrystalline chokes have become a preferred choice for engineers facing strict EMI compliance requirements.
Our 33x19x39mm through-hole nanocrystalline common mode choke series covers a broad range of inductance and current ratings, at 30mH the product could support rated current up to 5Amps . Beyond the standard portfolio, we provide unique customization advantages compared with larger competitors. For example, the impedance peak frequency can be adjusted based on customer requirements—whether shifting the Z peak from 1MHz up to 2MHz, or tuning it to lower ranges for specific system needs. We can also fine-tune inductance, current rating, or even modify dimensions upon request. Most importantly, our customization process is fast: instead of long lead times, we deliver tailored design proposals or even samples within 1–2 weeks, helping customers accelerate their project development.
If you are looking for a high-performance common mode choke solution with the flexibility of fast customization, we would be glad to support your design. Please contact us directly through the inquiry form on our website, and our team will provide you with the most suitable solution for your application.
Customization
Due to the solid background of our engineer team at ferrite powder territory, we could modify the core powder, design and produce the most suitable product to fit customer's applications. Except for the standard characteristic of our series specification, Coilmaster Electronics also offer the customization product with low minimum order quantity (MOQ), tighter tolerance, different inductance and frequency applications.
Leadtime
Coilmaster’s standard lead time is 6~8 weeks, in urgent case, the fast delivery program is available. For specific product series, we could send out the goods within 10 or 20 working days.
