Important Notice
We regret to inform you that we will be discontinuing our Ceramic Varistor (surge protection component) business in accordance with the schedule below. We sincerely apologize for any inconvenience this may cause and kindly request that you consider transitioning to alternative products
Since Marucon Electronics Co., Ltd.—prior to its merger with our company—commercialized ceramic varistors in 1971, our products have been widely adopted across a variety of equipment. However, due to significant changes in the business environment, we have taken the decision to withdraw from the ceramic varistor business.
We truly appreciate your support over the years and thank you for your understanding and cooperation.
