fit for the customer’s applications and products planned, as well as for the
planned application and use of customer’s third party customer(s). Customers
should provide appropriate design and operating safeguards to minimize the
risks associated with their applications and products.
Ampleon does not accept any liability related to any default, damage, costs or
problem which is based on any weakness or default in the customer’s
applications or products, or the application or use by customer’s third party
customer(s). Customer is responsible for doing all necessary testing for the
customer’s applications and products using Ampleon products in order to
avoid a default of the applications and the products or of the application or
use by customer’s third party customer(s). Ampleon does not accept any
liability in this respect.
Limiting values — Stress above one or more limiting values (as defined in
the Absolute Maximum Ratings System of IEC 60134) will cause permanent
damage to the device. Limiting values are stress ratings only and (proper)
operation of the device at these or any other conditions above those given in
the Recommended operating conditions section (if present) or the
Characteristics sections of this document is not warranted. Constant or
repeated exposure to limiting values will permanently and irreversibly affect
the quality and reliability of the device.
Terms and conditions of commercial sale — Ampleon products are sold
subject to the general terms and conditions of commercial sale, as published
at http://www.ampleon.com/terms, unless otherwise agreed in a valid written
individual agreement. In case an individual agreement is concluded only the
