These PTC products are employed in various applications. Examples include preventing serious accidents like fires by quickly responding to circuit failures, and operating as safe heaters to eliminate the need for temperature regulators. The scope of their uses is expected to expand in the future.

Since establishing the company, we have placed the utmost importance on quality control—essential for manufacturing—and continue to manufacture all products in Japan to ensure quality remains consistently high.
And the continuing support of our customers testifies to our original R&D and superior quality control.
