Key benefits Readytouse surface mounted components: SMD components are already soldered, reducing assembly steps. Flexible magnetic winding: The magnetic ring needs to be wound by the user, enabling the setting of specific inductance values. Clear winding guidance: The PCB shows how many turns each magnetic ring should have, facilitating accurate and repeatable builds. Defined footprint and size: Offers a consistent platform for integration with other components and boards. Specifications Net weight: 142 g SMD components: soldered on the board Magnetic ring: needs to be wound by the user; the winding count for each ring is printed on the PCB PCB size: 145 mm x 111 mm (excluding connectors) Notes The stated size excludes connectors. Any winding on the magnetic rings should follow the printed winding counts to achieve the intended characteristics. Use scenarios DIY electronics projects requiring a configurable magnetic core assembly: wind the rings to the desired turns to adjust inductance for prototypes. Prototyping magnetic components in RF or power electronics: use the PCB's printed winding counts to reproduce specific inductive configurations. Educational or lab demonstrations: students can learn how winding counts affect inductance by following the PCB guidance and varying turns.
