Product Description
Product Overview
The Unibody Inductor, MSM252012 series, is an integrated power inductor designed for high-current applications. It features a super low resistance and ultra-high current rating, realized by a metal dust core for high performance and saturation current. This inductor is compliant with ROHS standards and operates effectively up to 1MHz. It is 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.

Characteristics
- All test data is based on 25 ambient.
- DC current (A) that will cause an approximate T of 40.
- 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 actual application.
