SRP7030-4R7M 4.7µH Shielded Power Inductor with 9.6mΩ Low DCR 15.8A High Isat Ferrite Core High Current Low Loss Compact 7.3x7.3x3.0mm for Power Supplies
Features
n Shielded construction
n Unit height of 3.2 mm
n Inductance range: 0.1 to 10 μH
n Current up to 32.5 A
n RoHS compliant
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<sub>sat</sub>) 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.
