Strengths as a TDK Group Company

Accumulating more than 80 years of know-how and history, TDK was founded following the invention of ferrite, a vital component in the design of transformers and inductors, elements at the heart of any power supply development. TDK-Lambda benefits from TDK's expertise in ferrite and multilayer capacitors. Joint development and early access to advanced materials enable TDK-Lambda to greatly improve the efficiency and performance of our inclusive product offering.

In these challenging economic times, it is more tempting than ever to get quick savings by selecting a low-priced supplier. However, those quick savings can swiftly evaporate if problems develop, especially if the supplier has itself submitted to those same challenging times. If total cost of ownership is the goal, now seems an especially good time to ask some key questions regarding your power supply vendor:

  • Is this supplier financially sound?
  • Have they demonstrated their reliability?
  • Will the supplier always be there when you need them?
  • Are you comfortable in using their power supplies in your most critical applications?
  • Will they stand behind their product?
  • Are they readily accessible "real-time" to discuss your needs and to provide solutions?
  • What are the warranty terms and where are repairs performed?
  • Are you comfortable that the product documentation will support your safety agency filing and reporting?
  • Will you have access to higher level management if necessary?
  • What kind of liability insurance is available, and with what kind of insurance carrier?
  • If a serious problem does arise, do you have any realistic chance of pursuing a remedy?

TDK-Lambda would welcome the opportunity to demonstrate our values and low cost of ownership!
