Product Description
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 in distributed power systems and for field-programmable gate arrays. It features a sturdy assemblage design, high inductance, high current capability, low magnetic loss, low ESR, and small parasitic capacitance. The use of flat wire winding contributes to a low DC resistance, and the temperature rise current and saturation current are less influenced by the environment. Operating temperature range is -40 to +125.

Product Identification
MTP 2918S - XXX
- Series name
- Product dimensions
- Inductance
- Tolerance: M20%, N30%
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 application.
