Product Description
Product Overview
The MTP2918E-H series 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. These inductors feature 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 D.C. Resistance, and the temperature rise current and saturation current are less influenced by the environment.

Characteristics
- All test data is based on 25 ambient.
- DC current (A) that will cause an approximate T 40.
- DC current (A) that will cause L0 to drop approximately 20% Typ.
- Operating temperature range: -40~+125.
- The part temperature (ambient + temp rise) should not exceed 125 under worst-case operating conditions. Circuit design, component, PWB trace size and thickness, airflow, and other cooling provisions all affect the part temperature. Part temperature should be verified in the end application.
