Product Description
Product Overview
The Unibody Inductor, MSM252012 series, is a high-performance power inductor designed for low-profile, high-current applications. Featuring a metal dust core for excellent saturation characteristics and ultra-high current ratings, these RoHS-compliant inductors are ideal for battery-powered devices, DC/DC converters in distributed power systems, and DC/DC converters for field-programmable gate arrays. They offer super low resistance and operate effectively up to 1MHz.

Characteristics
- All test data is based on 25 ambient.
- DC current (A) that will cause an approximate ΔT 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 application.
Applications
- Low profile, high current power supplies.
- Battery powered devices.
- DC/DC converters in distributed power systems.
- DC/DC converters for field programmable gate array.
Features
- ROHS compliant.
- Super low resistance, ultra high current rating.
- High performance (Isat) realized by metal dust core.
- Frequency Range: up to 1MHz.
