Display of ordering codes for TDK Electronics products

The ordering code for one and the same product can be represented differently in data sheets, data books,

other publications, on the company website, or in order-related documents such as shipping notes, order

confirmations and product labels. The varying representations of the ordering codes are due to

different processes employed and do not affect the specifications of the respective products.
