Key Specifications

The Series for this component is identified as SF5035L-E18, which not only serves as its unique identifier but also indicates its specific design lineage and performance characteristics within KDM’s product portfolio. This series designation helps engineers quickly identify compatible or related parts for their designs. The Core Material is specified as Si-Fe / Sendust / High Flux. This is a crucial attribute, as the material dictates the magnetic permeability, saturation flux density, and core losses. Si-Fe (Silicon-Iron) offers good saturation characteristics and low cost, while Sendust provides higher permeability and lower core losses at medium frequencies. High Flux materials are engineered for high energy storage and low losses under high DC bias conditions, making this core versatile for demanding applications. The choice of this composite material ensures a balance of performance characteristics suitable for various power electronics. The Mounting Type is Through Hole, indicating that the core is designed for secure mounting onto a PCB using leads that pass through drilled holes, typically for larger components requiring robust mechanical support and thermal dissipation. This method ensures a strong physical connection and reliable electrical contact. The Component Type is clearly defined as a U/L Core, which describes its physical configuration – a U-shaped piece and a separate L-shaped piece that, when assembled, form a closed magnetic path. This design is often preferred for its ease of winding and assembly in specific transformer and inductor constructions. Finally, the Shape Dimensions (mm) are provided as 50 35 7.5 18.5. These values typically represent the outer length, outer width, height, and leg width respectively, or similar critical dimensions. These precise measurements are vital for mechanical integration into product enclosures and for calculating winding parameters, ensuring the component fits correctly within the design space and achieves the desired electrical performance.
