Customization
Our nanocrystalline common mode choke platform also supports a wide range of customization options for engineers who need precise electrical behavior.
Depending on the target EMI profile, we can fine-tune the Z-impedance curve, modify the inductance value, or increase the current rating whenever winding space permits.
For applications requiring lower copper loss or improved thermal stability, the coil can also be redesigned using flat-wire winding to reduce DCR and enhance high-current performance.
In addition to the standard core size, we offer larger magnetic cores, alternative material grades, and custom geometries to meet demanding EMC, temperature, or frequency requirements.
Because our team has extensive experience in nanocrystalline magnetic design, we are able to adjust the alloy characteristics and core construction to create different electrical behaviors within the same physical size—allowing customers to optimize performance without changing their mechanical layout.
If your project requires a specific inductance target, current capability, leakage profile, or impedance spectrum, we can support rapid evaluation and provide a tailored magnetic solution that matches your system’s EMI and thermal constraints.
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.
