EI3011-EI5423 Series Small reactor Compact, high-efficiency, low DC resistance. Stable inductance, low loss, good heat dissipation. Suitable for power supplies, lighting, and small electronic equipment.PCB transformer,PCB installation friendly type. In the circuit, the reactor plays a role of controlling harmonic current, improving output high-frequency impedance, efficiently suppressing dv/dt and reducing high-frequency leakage current . It helps protect the inverter and reduce noise of the equipment. In a relatively humid environment, moisture-proof is necessary. This product is installed in a custom enclosure and is insulated and moisture-proof through the packaging process. The iron core is fixed by welding process, which can effectively prevent noise and reduce energy loss.
