Korean Electronics Manufacturer Integrates Oval Nanocrystalline Core into Automotive Busbar and Y-Cap Systems

Dongguan JH Amorphous successfully partnered with a leading Korean electronics component manufacturer to deliver a customized oval nanocrystalline core solution for integration into plastic-embedded busbars and Y-capacitor modules used in electric vehicles.

The application required the magnetic core to be precisely embedded into an overmolded structure, ensuring effective common-mode noise suppression and high-frequency filtering in demanding automotive EMC environments.

Our oval nanocrystalline cores offer excellent performance advantages, including:

• High permeability and low core loss, ideal for filtering in high-frequency applications.

• Compact oval geometry, designed to fit within dual-channel plastic busbar layouts.

• Stable inductance performance under thermal and mechanical stress.

Throughout the project, Dongguan JH Amorphous provided full support from early-stage design alignment and custom mold matching to mass production with strict inductance control. We also helped ensure compliance with automotive reliability standards, including AEC-Q200.

The Korean client was highly satisfied with our:

• Engineering responsiveness during design and validation.

• Fast prototyping of oval core variants tailored to their enclosure.

• Consistent quality across batches during pre-production and ramp-up.

This project not only demonstrates our core customization capabilities but also reflects our ability to meet the automotive industry's rigorous EMC performance and production consistency requirements.
