Product Description
High Frequency Low Loss EE13 Horizontal SMPS Transformer for Power Supply PCB Board
Product Overview
The EE13 High-Frequency SMPS Transformer is a compact, high-efficiency magnetic component designed for modern, space-constrained switching power supplies (SMPS). Built with high-permeability ferrite cores and premium copper windings, the EE13 transformer delivers stable power transfer, excellent EMI suppression, and minimal power loss under high-frequency operation.
As a versatile power solution, it is fully customizable in inductance, turns ratio, pin configuration, and insulation voltage to meet your exact OEM/ODM design requirements.
