Ceramic Resonators/Filters, both surface mount and through-hole type, are a much different frequency control solution than that of a crystal based device. Not only are there “matching” issues to specific integrated circuits and processors with ceramic based piezoelectric components but for multiple reasons ceramics are not the most advantageous nor robust frequency control solution for certain applications. In addition, ECS does not approve the use of its ceramic products in Automotive, Military, Avionics, Life Sustaining or Life Support systems or any other related medical application. If the customer chooses to use this product in one or more of the noted applications without the written consent of ECS, Inc., ECS, Inc. shall be held harmless, and given release of liability and indemnification from claims of any nature. Please complete the following and submit this form as soon as possible. ECS Part Number Estimated Annual Usage Has this part already been approved for this application? Has this part been ordered previously for this application? End Customer Yes No Yes No Application Details You Must Be Specific or this may be returned for more information. I certify that the above information is true and correct to the best of my knowledge and acknowledge that ECS will be held harmless if this item is used in the restricted applications noted above. __________________________________________ Company Name __________________________________________ Print Your Name __________________________________________ Title ** If this item will be used by a 3rd party ECS may require a form be completed and signed by all parties. __________________________________________ Signature Date To be completed by ECS Inc., International Approved: Disallowed: Date: ____________________ Approved By: ______________________________________ Please direct any further inquires to Brad Slatten at [email protected] or Carla Williams at [email protected] .
