Changes to Part Numbers
TAIYO YUDEN will implement changes to the part numbers of our products.
By changing the part numbers, we will be able to clarify the target market and equipment in which our products are used,and recommend our customers appropriate products for their intended purposes as possible.
In addition, in making the changes, we have established new common rules that will make it easier for our customers tounderstand and search for part numbers and recommended applications of our products.
※Start shipping samples and accepting orders using the new part numbers : From October 1, 2021
※Start shipping our products with the new part numbers : From April 1, 2022 (estimated)

When ordering our products newly used by you, please check the explanatory materials for the part numbering system,
precautions for use, etc. and use the new part numbers of the corresponding products.
