Product Description
The TDK B66305G0000X127 is a high-quality N27 ferrite transformer core with an E 13/7/4 configuration and an AL rating of 800 nH, making it ideal for demanding power and miniature transformer applications in industrial electronics.
This E core type achieves high magnetic permeability, offering efficient suppression of common mode noise as well as precise inductance for broadband transformers. The N27 material used in this core delivers a high saturation flux density, minimal power loss, and robust performance under varied electrical loads.
Engineered with a compact form factor of 12.6 mm length, 3.7 mm width, and 6.5 mm depth, the core enables optimized assembly in high-density electronic circuits, while supporting reliable operation up to 155°C. Its construction adheres to IEC 61246 standards, ensuring consistency, safety, and compatibility with global requirements.
The AL rating of 800 nH provides accurate inductance when paired with the appropriate coil former, supporting transformer designs that demand minimal losses and steady magnetic characteristics in both power and miniature transformer circuits.
Typical use cases include the assembly of power transformers, miniature transformers, common mode chokes, and other magnetic components where broadband applications and consistent performance are critical. Its ferrite composition makes it suitable for both industrial and commercial electronics manufacturing, including power supplies, signal conditioning units, and energy conversion modules.
This product does not include the coil former, which can be separately selected for E 13/7/4 cores as per your transformer design requirements. Reliability and durability are further assured by the tight specification tolerances and material quality synonymous with TDK.
