Product Overview
The MTP2918E-H series is a high-current power inductor designed for applications requiring low profile and robust performance. It features an assemblage design with a sturdy structure, offering high inductance, high current handling, low magnetic loss, low ESR, and small parasitic capacitance. The flat wire winding contributes to a low DC Resistance. Key advantages include saturation current and temperature rise current that are less influenced by the environment. This series is ideal for low-profile, high-current power supplies, battery-powered devices, DC/DC converters in distributed power systems, and DC/DC converters for field-programmable gate arrays.
