Product Description
Unibody Power Inductor - MS0840-150M
Product Overview
This Unibody Power Inductor, model MS0840-150M, is a high-performance magnetic component designed for demanding applications. Featuring a metal dust core, it offers super low resistance and ultra-high current rating, enabling high saturation current (I sat) capabilities. Its low profile and robust design make it ideal for compact and power-efficient electronic systems. This inductor is compliant with ROHS standards and operates effectively across a wide frequency range up to 1MHz.
Applications:
- Low profile, high current power supplies.
- Battery powered devices.
- DC/DC converters in distributed power systems.
- DC/DC converters for field-programmable gate arrays (FPGAs).
