Key Attributes
Model Number:
MTP2918S-3R3M-C
Product Description
MTP2918S-C Series High Current Power Inductor
Product Overview
The MTP2918S-C series is a high-current power inductor designed for demanding applications. It features a sturdy construction with flat wire winding, contributing to low D.C. Resistance (DCR), high inductance, and high current handling capabilities. The inductors offer low magnetic loss, low ESR, and small parasitic capacitance. Their saturation current and temperature rise current are less influenced by environmental factors, ensuring reliable performance across a wide operating temperature range of -40 to +125. Ideal for low-profile, high-current power supplies, battery-powered devices, and various DC/DC converter applications, including those in distributed power systems and for field-programmable gate arrays (FPGAs).

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.
