We would like to provide an answer to the question, "Do Matsusada Precision's products contain polychlorinated biphenyls (PCBs)?" Our internal investigations have confirmed that no components containing PCBs have been used in our products since 1985.

It has been reported that capacitors manufactured by Nichicon Corporation may contain trace amounts of PCBs, but we do not use such products.

We have received the following response from Nichicon Corporation.
"Capacitors that may contain trace amounts of PCBs are oil-filled capacitors (both high and low voltage) for electric power and industrial equipment. Aluminum electrolytic capacitors and film capacitors for electronic equipment do not contain PCBs (oil is not used) and are not included."

PCBs were generally used as insulating oil in transformers and capacitors, but their production and import was banned in Japan in 1972.
