Service Life: Service Life of Circuit Products

The life of each of Oriental Motor's circuit products is determined by the aluminum electrolytic capacitor inside the product. Our circuit products are designed so that their life will be reached after 5 years min. when the product is used continuously under an ambient temperature of 40 °C. (Excluding certain products.)
In addition, an aluminum electrolytic capacitor generally exhibits the characteristics according to the "Arrhenius equation." Specifically, as shown in the figure below, a temperature rise of 10 °C reduces the life of an aluminum electrolytic capacitor to half, while a temperature drop of 10 °C will extend the life to twice as long.
Since the lifetime of a circuit product varies depending on the operating environment and conditions, Oriental Motor recommends that the curve shown in the figure below be used to determine the need for preventive maintenance to keep the product free from failure.
