Product Description
Product Overview
The MTF1810 series is a high-current power inductor designed for various electronic applications. Featuring a sturdy construction and flat wire winding for low DC resistance, these inductors offer high inductance, high current handling, low magnetic loss, low ESR, and small parasitic capacitance. They are suitable 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. The performance of saturation current and temperature rise current is less influenced by environmental factors.

Characteristics
- All test data is based on 25°C ambient.
- DC current (A) that will cause an approximate ΔT 40°C.
- DC current (A) that will cause L0 to drop approximately 30% Typ.
- Operating temperature range: -40°C ~ +125°C.
- The part temperature (ambient + temp rise) should not exceed 125°C 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.
