We would like to introduce the "SCCR-compliant noise filters" that we handle. In response to the expanding semiconductor industry, manufacturers of manufacturing equipment, and the demands for equipment in North America, we are enhancing our lineup of high SCCR-compliant products. By using SCCR-compliant products, you can contribute to reducing the examination time and costs associated with safety standard certification. 【Product lineup (partial)】 <Single-phase noise filters> ■ EA series 1-stage filter ■ ES series 1-stage filter ■ NA series 1-stage filter ■ NB series 2-stage filter *For more details, please refer to the related links or feel free to contact us.

This document provides a detailed explanation using diagrams about the necessity of SCCR and the reasons why a high SCCR is required. It contains valuable information, so please take a moment to read it.

We would like to introduce basic information about noise, which is frequently consulted in our customer support department, as well as a simple measurement tool called "CESA" (developed in-house and not for sale) that visualizes "invisible noise." Based on the know-how cultivated as a power supply manufacturer, we clearly explain the types of noise, their impacts, and the first steps for effective measures that can be useful on-site, along with examples of confirmed effectiveness. We encourage you to read it! 【Contents】 1. Why is noise a problem? 2. Types of noise 3. Concepts and realities of noise countermeasures 4. Visualizing noise with the simple measurement system "CESA" 5. Examples of confirmed effectiveness of countermeasures 6.
