Product Description
Product Overview
The MTM1350-7R2M is a high current power inductor from Shenzhen Motto Technology Co., Ltd. Designed for low profile, high current applications, it features a sturdy assemblage design, 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 power supply applications, including battery-powered devices, DC/DC converters in distributed power systems, and DC/DC converters for field-programmable gate arrays. Its temperature rise and saturation currents are less influenced by environmental factors.
