Product Overview
The MTP2920-3R3MC-QZ is a high-current power inductor designed for low-profile, high-current power supplies, battery-powered devices, and DC/DC converters in distributed power systems and for field-programmable gate arrays. It features an assemblage design with a sturdy structure, offering high inductance, high current capability, low magnetic loss, low ESR, and small parasitic capacitance. The use of flat wire winding contributes to a low DC Resistance. Environmental factors have less influence on its temperature rise current and saturation current.
