Applications

1:DC-DC Converters: Primarily used as the output choke or energy storage inductor in high-current Buck (step-down) converters.

2:Voltage Regulator Modules (VRMs) for servers, workstations, and desktop computers.

3:Networking equipment, telecom infrastructure, and base stations.

4:Power management for graphics cards and gaming consoles.

5:Power circuits in various industrial and automotive electronics.

Description

1:High Current Capability: Its key advantage is the ability to handle a high saturation current (I_sat) of 15.8A. This makes it ideally suited for power stabilization and filtering in circuits powering CPUs, GPUs,  and other high-current loads.

2:Low DC Resistance (DCR): It features an exceptionally low typical DC resistance of just 9.6mΩ. This minimizes power losses (I²R losses), thereby increasing power conversion efficiency and reducing heat generation within the component itself.

3:Shielded Construction: The magnetically shielded structure effectively suppresses electromagnetic interference (EMI) and reduces magnetic field leakage to nearby sensitive circuits. This simplifies board design and aids in passing EMC compliance tests.

4:Compact Footprint: With dimensions of just 7.3mm x 7.3mm x 3.0mm, it offers high power density in a minimal PCB area. This makes it perfect for space-constrained applications like slim notebooks, server motherboards, and networking equipment.

5:Robust Performance: The use of a robust ferrite core material and a heat-resistant plastic casing ensures high reliability and long-term stability under demanding conditions. It typically features a wide operating temperature range, often from -40°C to +125°C or higher, suitable for industrial-grade applications.

6:Low-Loss Design: The combination of low DCR and optimized core material results in low overall power loss at switching frequencies, contributing to higher overall system efficiency.
