Component Specifications

Definition
Termination pins are precision-engineered conductive components designed to provide reliable electrical termination points in magnetic modules such as transformers, inductors, and chokes. They serve as interface elements between the magnetic core/winding assembly and external circuitry, ensuring secure mechanical attachment and consistent electrical conductivity. These pins are typically inserted into bobbin or core structures and may be soldered, welded, or crimped to establish permanent connections.
Working Principle
Termination pins function by providing a conductive pathway between the internal windings of a magnetic component and external circuit connections. When installed, they create a low-resistance interface that allows electrical current to flow into and out of the magnetic module while maintaining mechanical stability. The pins may incorporate features such as flanges, barbs, or knurls to enhance retention within insulating materials.
Materials
Copper alloys (C11000, C10200), brass (C26000), phosphor bronze (C51000), or beryllium copper (C17200) with optional tin, silver, or gold plating for corrosion resistance and improved solderability. Insulation materials may include nylon, PBT, or LCP for bobbin integration.
