(1/18) LLC Resonance Power Transformer SRX Series Conformity to RoHS Directive Development Concept Compliant with worldwide safety standards, this is a small and thin transformer with the advantages of effective use of low-loss ferrite material. MATERIAL Optimized materials and core shapes have been developed. The necessary power can be transmitted with a small number of windings. While optimizing materials, TDK has further improved its proprietary core shape to develop a new-type ECO core. The transformer has been downsized considerably, and its temperature increase has also been curbed. MANUFACTURING METHOD Since the ECO Series supports automatic winding, the product is of a high quality and can be manufactured stably. It is designed to support automatic winding, which enables a remarkable reduction in the loss generated to achieve a proficient in manual winding until stable production. In addition, the characteristic variations of the winding wire and creepage tape have largely been removed, stabilizing the transformer's characteristics. OPTIMIZATION DESIGN Using design tools developed with TDK's comprehensive know-how, high-precision design has been achieved in a short period of time. 1) For optimization design and high-quality stable production, customers can use a specification request form. If you provide the necessary information in the form, you will receive the optimization design in a short time. 2) TDK recommends design with a standard core gap (AL-value) for optimization and shorter trial and mass production lead time. Design is simple as each shape retains its GAP, AL-value, and K parameters beforehand. ENVIRONMENT The SRX series is RoHS directive-compliant product. • Ferrite cores, bobbins, cases, etc. are not sold individually. • Conformity to RoHS Directive: This means that, in conformity with EU Directive 2002/95/EC, lead, cadmium, mercury, hexavalent chromium, and specific bromine-based flame retardants, PBB and PBDE, have not been used, except for exempted applications. • All specifications are subject to change without notice. 003-02 / 20100924 / e636_srx.fm (2/18) LLC Resonance Power Transformer SRX Series Conformity to RoHS Directive TDK now provides a characteristically thin resonance LLC resonance power transformer. In order to develop this transformer, TDK made effective use of low loss performance (which is a feature of the PC47 family), optimized the structure of the core and the bobbin, and utilized its proprietary automatic winding industrial method. FEATURES • A low height (8 to 31.5mm in height) is achieved. • Large power is achieved in a small shape. • The automatic winding industrial method is adopted. • It is a product conforming to RoHS directive.
