TDK EFD25 Half Ferrite Core, N87 Material Grade

The TDK EFD25 Half Ferrite Core is an ungapped transformer core manufactured from N87 material grade. Designed with a flattened, lower centre leg, this E-core is specifically engineered for especially flat transformer designs, making it highly suitable for DC/DC converters.

Featuring an effective cross-sectional area of 58mm² and an inductance factor of 2µH, this ferrite core delivers reliable magnetic performance. Please note that the magnetic properties of NiZn materials can change irreversibly in high magnetic fields, which should be considered during circuit design.

Ideal for industrial applications, this half core offers robust and consistent performance. With compact dimensions of 43mm in height, 33mm in width, and 15mm in depth, it provides a space-efficient solution for modern electronic assemblies. The core weighs just 8 grams, ensuring minimal impact on the overall weight of the assembled component.
