Important Notes The following applies to all products named in the publication ds Some parts of this publication contain statements about the sustainability of our products for certain areas of application These statements are based on our knowledge of typical requirements that are often placed on our products in the areas of application concerned We nevertheless expressly point out that such statements cannot be regarded as binding statements about the sustainability of our products for a particular customer application As a rule TCI is either unfamiliar with individual customer applications or less familiar with them than the customers themselves For these reasons it is always ultimately incumbent on the customer to check and decide whether a TCI product with the properties described in the product specification is suitable for use in a particular customer application We also point out that in individual cases a malfunction of passive electronic components or failure before the end of their usual service life cannot be completely ruled out in the current state of the art even if they are operated as specified In customer applications requiring a very high level of operational safety and especially in customer applications in which the malfunction or failure of a passive electronic component could endanger human life or health e g in accident prevention or life saving systems it must therefore be ensured by means of suitable desi
