Customization is available; please consult us for various modifications. Common mode chokes using nanocrystal cores. Excellent low frequency properties. Stable performance over a wide temperature range. SEIWA offers special ordered CMC.

● The ultra-thin shape contributes to space-saving and helps achieve a lightweight and compact design. ● Effectively suppresses radiated noise from the FPC. ● Has minimal impact on transmission signals and is easy to handle.

It is rich in flexibility and easy to handle. Made of conductive coated resin, it excels in flexibility, allowing for smooth cable bundling and fixing operations, as well as measures against electromagnetic noise in cables.

Product Outline and Features This product uses a new nanocrystal material for the core, allowing for greater effectiveness. By adopting the nanocrystal common mode choke coil, it is possible to reduce the capacitance of surrounding capacitors, enabling space-saving design. This is a common mode choke coil made with nanocrystalline soft magnetic material. Compared to ferrite core CMC, it has high noise attenuation characteristics in the kHz range. It ensures stable impedance characteristics over a wide temperature range. Customization is available; please consult us for various modifications. Common mode chokes using nanocrystal cores. Excellent low frequency properties. Stable performance over a wide temperature range. SEIWA offers special ordered CMC.

1. Compared to conventional ferrite cores, the characteristics in the 500MHz to 5GHz range have been improved. 2. Noise countermeasures can be implemented as an add-on rather than on-board. 3. It is less affected by temperature and maintains stable performance even in high-temperature environments (up to 150°C), including self-temperature rise.

The "E21NFB Series" is an EMI filter that is highly effective for mitigating conducted noise in the frequency range of 150 kHz to 30 MHz. It is compact, lightweight, and low-profile, achieving effective noise mitigation while saving space. It features a spring-up terminal block that allows for easy installation and comes with a cover for safe use. Additionally, it has obtained UL, EN, and CSA certifications, making it suitable for equipment exported to North America and the EU. 【Features】 ■ Complies with international safety standards ■ Compact, lightweight, and low-profile for space-saving ■ High efficiency and safety in installation shape ■ Utilizes a spring-up terminal block ■ Comes with a cover *For more details, please refer to the PDF document or feel free to contact us.

"Noise Finder" is a noise countermeasure product that has the functionality of a 2-channel spectrum analyzer and calculates the contribution from two types of signals. It operates based on a spectrum analyzer, making it easy to identify noise sources by viewing the value (noise estimate) obtained by multiplying the contribution by the spectrum of CH1. In conventional noise visualization systems, it was difficult to identify the path of noise sources, but the visualization system of this product allows for path identification. 【Features】 ■ Usable not only on the circuit board but also on cables and enclosures ■ Functions as a 2-channel spectrum analyzer ■ Determines whether two types of noise are at the same frequency and identifies the true noise source ■ Operable based on a spectrum analyzer ■ Displays the spectrum and contribution of CH1 and CH2 ■ The visualization system of this product allows for path identification *For more details, please refer to the PDF document or feel free to contact us.

"Mirror Star" is a reworkable and easy-to-apply heat-insulating sheet. It features a non-adhesive suction sheet that does not dirty the contact surface, with high solar reflectivity and excellent weather resistance. It can be provided at a lower cost compared to applying heat-insulating paint. Made from acrylic resin and PET, the color is beige. Please feel free to contact us for inquiries. 【Features】 ■ Reworkable and easy to apply ■ Non-adhesive suction sheet that does not dirty the contact surface ■ High solar reflectivity and excellent weather resistance ■ More cost-effective than applying heat-insulating paint ■ Made from environmentally friendly acrylic resin and PET *For more details, please refer to the PDF document or feel free to contact us.

Our Components Division has renewed the catalog for electromagnetic noise countermeasures, wiring protection materials, and LED lighting modules to further promote our "solution-oriented sales" approach, which ensures that we accurately capture our customers' diverse needs and connect them to problem-solving through our products and services. In this renewal, we aimed to create a structure that is easy to understand for first-time visitors to our company by organizing service explanations and highlighting our strengths. Additionally, we have integrated the synergies of our product groups to clearly convey our value proposition of being able to provide consistent support from upstream to downstream in manufacturing. We have also included case studies and specific examples to make the concept of our solution proposals more accessible. We hope that this catalog serves as an opportunity for you to learn about our "product strength × proposal strength" and contributes to solving your challenges.
