Display of ordering codes for EPCOS products
The ordering code for one and the same product can be represented differently in data sheets,
data books, other publications and the website of EPCOS, 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.
Detailed information can be found on the Internet
under www.epcos.com/orderingcodes.
