Electrical Standerds Compliance Service

Consulting and Test Services for the following

Mitsubishi Materials is pleased to offer customers surge absorber countermeasure solutions.


•During development, the product cannot pass UL inspection.
•The product has been damaged by lightning and you'd like to take preventative measures.

Because conditions differ depending on the development model/product variation, it is beneficial to perform actual surge tests.


At the Mitsubishi Materials Ceramics Factory, our engineers, in attendance with the customer, can perform surge tests on a product and offer surge counter-measure solutions. If the customer is unavailable or unable to attend, there is also an option to have the product sent and tested by our engineers alone. Once the test is complete, we can quickly return the product along with a detailed report on the counter-measure solutions.

At our Ceramics factory, it is possible to base the testing on a variety of standards, including IEC61000-4-2,IEC61000-4-5,JEC,JIS,UL ,ITU-T and more.

Please contact your sales representative with any problems you may have.
