Product Overview
The MTM1480-1R8M is a high current power inductor from Shenzhen Motto Technology Co., Ltd. Designed for low profile applications, it features a sturdy structure, high inductance, high current handling, low magnetic loss, low ESR, and small parasitic capacitance. The use of flat wire winding contributes to a low DC resistance. This inductor is suitable for various applications including 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. Its performance regarding temperature rise current and saturation current is less influenced by the environment.
