Datasheet E10 EM (TDK) - 7

SMD transformers E10 EM series B78307A*A003 Preliminary data Cautions and warnings
- Please note the recommendations in our Inductors data book (latest edition) and in the data sheets. - Particular attention should be paid to the derating curves given there. - The soldering conditions should also be observed. Temperatures quoted in relation to wave soldering refer to the pin, not the housing. - If the components are to be washed varnished it is necessary to check whether the washing varnish agent that is used has a negative effect on the wire insulation, any plastics that are used, or on glued joints. In particular, it is possible for washing varnish agent residues to have a negative effect in the long-term on wire insulation. Washing processes may damage the product due to the possible static or cyclic mechanical loads (e.g. ultrasonic cleaning). They may cause cracks to develop on the product and its parts, which might lead to reduced reliability or lifetime. - The following points must be observed if the components are potted in customer applications: - Many potting materials shrink as they harden. They therefore exert a pressure on the plastic housing or core. This pressure can have a deleterious effect on electrical properties, and in extreme cases can damage the core or plastic housing mechanically. - It is necessary to check whether the potting material used attacks or destroys the wire insulation, plastics or glue. - The effect of the potting material can change the high-frequency behaviour of the components. - Many coating materials have a negative effect (chemically and mechanically) on the winding wires, insulation materials and connecting points. Customers are always obligated to determine whether and to what extent their coating materials influence the component. Customers are responsible and bear all risk for the use of the coating material. TDK Electronics does not assume any liability for failures of our components that are caused by the coating material. - Ceramics / ferrites are sensitive to direct impact. This can cause the core material to flake, or lead to breakage of the core. - Even for customer-specific products, conclusive validation of the component in the circuit can only be carried out by the customer.
Display of ordering codes for TDK Electronics products
The ordering code for one and the same product can be represented dif erently in data sheets, data books, other publications, on the company website, or in order-related documents such as shipping notes, order confirmations and product labels.
The varying representations of the ordering codes are due to different processes employed and do not affect the specifications of the respective products
