Product Overview
The MTP2918S-C series is a high-current power inductor designed for low-profile, high-current power supplies, battery-powered devices, and DC/DC converters. It features a sturdy assembly design with flat wire winding for low D.C. Resistance. Key benefits include high inductance, high current capability, low magnetic loss, low ESR, and small parasitic capacitance. The saturation current and temperature rise current are less influenced by environmental factors. This series is suitable for applications such as DC/DC converters in distributed power systems and for field-programmable gate arrays.

Characteristics:
- All test data is based on 25 ambient.
- DC current (A) that will cause an approximate T40.
- DC current (A) that will cause L0 to drop approximately 30% 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.
