Cautions and Warnings: The following conditions apply to all goods within the product series of STAR-RING of Würth Elektronik eiSos GmbH & Co. KG: General: All recommendations according to the general technical specifications of the data sheet have to be complied with. The usage and operation of the product within ambient conditions, which probably alloy or harm the component surface, has to be avoided. The packaging of the product is to encase the needed humidity of the plastic housing. To ensure the humidity level, the products have to be stored in this delivered packaging. If not, the products are losing their humidity. In this case you can re-condition the components according to the internal standard WE1581 to ensure the necessary humidity in the plastic. For further information about this internal standard please refer to the document ‘WE-Standard 1581’ which can be downloaded from the respective product page on our website. To ensure the operating mode of the product, the ambient temperature at processing (when the part will be mounted on the cable) has to be in the range of 15 to 35 °C.Before mounting, the part should be stored for one hour in this condition.The responsibility for the applicability of customer specific products and the use in a particular customer design is always within the authority of the customer. All technical specifications for standard products do also apply to customer specific products. Direct mechanical impact to the product and the forcible closing of this shall be prevented as the ferrite material of the ferrite body or the plastic housing could flake or in the worst case it could break. Product specific: Follow all instructions mentioned in the data sheet, especially: • The cable diameter must be pointed out, otherwise this will void the warranty. • Violation of the technical product specifications such as exceeding the nominal rated current will void the warranty. The general and product specific cautions comply with the state of the scientific and technical knowledge and are believed to be accurate and reliable; however, no responsibility is assumed for inaccuracies or incompleteness.
