Product Description
Product Overview
The MS1050-220M-P is a Unibody Power Inductor designed for high-current applications. It features super low resistance and an ultra-high current rating, realized by a metal dust core for high performance (I sat). This inductor 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. It operates within a frequency range of up to 1MHz and is ROHS compliant.

Characteristics
- Ambient Temperature: 25 for all test data.
- I rms Definition: DC current (A) that will cause an approximate T of 40.
- I sat Definition: DC current (A) that will cause L0 to drop approximately 35% Typ.
- Operating Temperature Range: -55 to +125.
- Part Temperature Limit: Should not exceed 125 under worst-case operating conditions (ambient + temp rise). Circuit design, PWB trace size and thickness, airflow, and other cooling provisions affect part temperature. Part temperature should be verified in the actual application.
