The EE 13x10 transformer is a miniature, high-frequency ferrite core transformer designed for low-power Switch Mode Power Supply (SMPS) applications. With its compact EE13 core geometry—approximately 13mm in width and 10mm in height—it’s ideal for space-constrained designs such as mobile chargers, LED drivers, and small consumer electronics.

This transformer typically operates in the 10kHz to 1MHz frequency range, supporting output power levels from 0.5W to 6W depending on the winding configuration and core material. It features enameled copper or Litz wire windings, optimized for minimal high-frequency resistance and efficient energy transfer.

Thanks to its low profile and high thermal stability, the EE 13x10 transformer ensures reliable performance across a wide temperature range—from -40°C to +125°C—making it suitable for both indoor and rugged environments. It’s often used in flyback, forward, and gate drive topologies, and supports RoHS-compliant materials for eco-conscious designs.
