Legacy Products

TDK-Lambda has been providing AC-DC power supplies, DC-DC converters, Programmable (Laboratory) power supplies, High Voltage power supplies and EMC/EMI filters for over 70 years. Our aim is to continue to offer a product line for as long as it is economically and practically possible. Many of our power supplies have been on the market in excess of 20 years.

Products not recommended for new designs

In order to minimize customer impact from discontinued lines, we identify those products which are not recommended for use in new designs (NRND). This does not mean that these products are about to become obsolete. In many cases these products have a large customer base and will remain in production for many years. Usually, we have newer alternatives available that are more cost effective and offer enhanced technical performance. Please contact us if you require more specific information about any of the products listed here.

Legacy products library

This has two purposes. First, it provides a map from older and obsolete products to their current counterparts. Secondly, it links to old catalog data allowing you to access datasheets from our long history.

You can locate your product by series name. Highlighted catalog names link to PDFs of old catalog datasheets. These pages are from North American catalogs unless otherwise noted. If you have any questions, please call 800-Lambda4 for assistance.
