Product Overview
The MTP2920 series is a high-current power inductor designed for demanding applications. Featuring an assemblage design with a sturdy structure, it offers high inductance, high current handling, low magnetic loss, low ESR, and minimal parasitic capacitance. The flat wire winding construction ensures exceptionally low DC resistance, and its temperature rise and saturation currents are minimally affected by environmental conditions. This series is ideal for low-profile, high-current power supplies, battery-powered devices, DC/DC converters in distributed power systems, and DC/DC converters for field-programmable gate arrays.

Operating Conditions & Characteristics
- Ambient Temperature: All test data based on 25.
- Operating Temperature Range: -40 to +125.
- Maximum Part Temperature: Should not exceed 125 under worst-case operating conditions (ambient + temp rise). Component temperature is influenced by circuit design, PWB trace size and thickness, airflow, and other cooling provisions. Verification in the end application is recommended.
- Saturation Current Definition: DC current that causes L0 to drop approximately 30% (Typ).
- Temperature Rise Current Definition: DC current that causes an approximate T of 40.
