Product Description
Product Overview
The MSM252010 series is a range of unibody power inductors designed for high-performance applications. These inductors feature a metal dust core for high saturation current and super low resistance, enabling ultra-high current ratings. 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 series is ROHS compliant and operates efficiently 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 to +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 end application.
