Product Description
Product Overview
The MTP2918S-C series is a high-current power inductor designed for low-profile, high-current power supplies and battery-powered devices. It is suitable for DC/DC converters in distributed power systems and for field-programmable gate arrays. Key features include a sturdy, assembled structure, high inductance, high current capability, low magnetic loss, low ESR, and small parasitic capacitance. The use of flat wire winding contributes to a low DCR, and the temperature rise current and saturation current are less influenced by environmental factors.

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 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.
