Product Description
Product Overview
The MSM252010 series is a range of unibody power inductors designed for high-performance applications. These inductors feature a super low resistance and ultra-high current rating, realized by a metal dust core, making them suitable for low profile, high current power supplies, battery-powered devices, and DC/DC converters in distributed power systems and for field-programmable gate arrays. They are ROHS compliant and operate efficiently up to 1MHz.
Product Attributes
- Brand: (Coilmx)
- Product Type: Unibody Power Inductor
- Certifications: ROHS compliant
- Core Material: Metal dust core
- Marking: NO Marking on top of the body.

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 application.
