Seiko Electric Co., Ltd. will exhibit at the 2018 Nagoya Automotive Technology Exhibition.

Common mode choke coil using nanocrystalline soft magnetic materials is highly effective for low-frequency noise countermeasures!

Product Outline and Features The core material uses a new nanocrystal material, 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 designs. This is a common mode choke coil made with nanocrystalline soft magnetic material. Compared to ferrite core CMC, it has excellent 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.

Since a ground connection is not required, no design changes to the FPC are necessary.

Product Outline and Features No design change of the FPC is required due to the absence of a ground connection. Can be incorporated into the FPC manufacturing process as it can withstand solder reflow. Optimal for partial attachment to the FPC (see supplementary reference).

It is extremely effective for countermeasures against conducted noise below 150 kHz! A large size has also been added to the lineup, making it compatible with large-diameter cables.

Product Outline and Features It has excellent impedance characteristics below 150kHz. High permeability contributes to the miniaturization of the core. It ensures stable impedance characteristics over a wide temperature range. A larger size has been added to the lineup, making it compatible with large diameter cables.

Sekiguchi Iron Works Co., Ltd. will exhibit at the "Environmental Industry Expo 2025" held at S-Bird in Iida City, Nagano Prefecture. This exhibition aims to pave the way for a sustainable future from the local community. It is a trade fair for environmental-related industries originating from the Minami-Shinshu region of Nagano Prefecture. Our company will introduce next-generation solutions for reducing environmental impact and effectively utilizing energy, including our "smokeless small incinerator" and "stove," along with product panels and case studies. No pre-registration is required, and admission is free. We sincerely look forward to your visit.

Recently, fine bubbles, which are tiny bubbles smaller than 100 μm and are referred to as "fine bubbles," have attracted attention in various fields such as the environment, agriculture, food, fisheries, and medicine, due to their ability to impart various functions to liquids. Fine bubbles are classified into two types based on their size: microbubbles and ultrafine bubbles. Recently, there has been a growing interest in ultrafine bubbles, which have a lifespan of several weeks to months. However, listening to the voices of researchers and users reveals some skepticism, which has become one of the issues hindering the spread of fine bubble technology. On the other hand, we have challenged the elucidation of the stabilization mechanism of ultrafine bubbles from a new perspective by enabling the control of number density exceeding 10 billion particles/mL without pressure or concentration operations using our ultrafine bubble generation technology. In this seminar, we will provide a fundamental explanation of fine bubble technology, including the basic physical properties, characteristics and functions, device technology, measurement and evaluation methods, and case studies, to promote research and utilization of fine bubbles based on a correct understanding.

Sekiguchi Iron Works Co., Ltd. will exhibit at the "Minami-Shinshu Environmental Messe 2025" held at S-Bird in Iida City, Nagano Prefecture. This exhibition will be held simultaneously with the "Environmental Industry Trade Fair" taking place the day before. It will be held over the weekend, with many family-friendly events planned. We encourage those who usually find it difficult to visit to take this opportunity to come. Our product exhibition area is located about 10 minutes from the venue. We sincerely look forward to your visit.
