Materials Disclosure Disclaimer

Note: Even though all possible efforts have been made to provide you with the most accurate information, we can not guarantee to its completeness and accuracy due to the fact that the data has been compiled based on the ranges provided and some information that may not have been provided by the subcontractors and raw material suppliers to protect their business proprietary information.

Based on the above considerations, this information is provided only as estimates of the average weight of these parts and the anticipated significant toxic metals components. These estimates do not include trace levels of dopants and metal materials contained within silicon devices in the finished products.

There is no intentional use of Cadmium, Mercury, Hexavalent Chromium, Polybrominated biphenyls (PBBE), Polybrominated diphenyl ethers (PBDE), and four phthalates Bis(2-ethylhexyl) phthalate (DEHP), Butyl benzyl phthalate (BBP), Dibutyl phthalate (DBP), Diisobutyl phthalate(DIBP) (9 of the 10 RoHS banned substances) in this or any of our other products.
