Product Overview
The MSM252010 series is a range of unibody power inductors designed for high-current applications. These components feature super low resistance and ultra-high current ratings, realized by a metal dust core for high performance. They are suitable for use in 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 inductors are ROHS compliant and operate effectively at frequencies up to 1MHz.

Characteristics
- All test data is based on 25 ambient.
- DC current (A) that will cause an approximate ▵T40.
- DC current (A) that will cause L0 to drop approximately 30% Typ.
- Operating temperature range: -55~+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.
