High Current SMD Shielded Inductor SDRH6D28/6D38 Series Low Resistance for Automotive Systems and LCD TVs

The SDRH6D28/6D38 series magnetic shielded SMD power choke uses a magnetic shield structure and square flat package design. It effectively reduces EMI and is suitable for high-density PCB layouts and space-constrained applications. The product offers excellent mechanical strength and thermal stability, capable of withstanding reflow soldering temperature changes and external mechanical stress. The miniature size, high energy storage, and low resistance characteristics make it an ideal inductor choice for PDA and DC-DC switching power supplies, suitable for high-current operation (up to 3.2A). It is widely used in video digital cameras, communication systems, automotive power systems, LCD/PDP TVs, hard disk drives, network systems, and computer peripherals.

Q: What are the advantages of the magnetic shield structure?

A: The magnetic shield structure uses a closed magnetic circuit design to confine magnetic flux inside the core. It effectively reduces leakage flux and electromagnetic interference to nearby sensitive circuits. In high-density PCB layouts such as communication equipment and automotive electronics, shielded inductors significantly improve system EMC performance.

Q: What is the maximum rated current of this series?

A: This series offers high current capacity up to 3.2A, suitable for high-current DC-DC converters and power management applications. When selecting, we recommend choosing a rated current at least 20% higher than the maximum operating current to prevent performance degradation caused by core saturation at high temperatures.

Q: What is the significance of excellent mechanical strength and thermal stability?

A: Excellent mechanical strength ensures the inductor is less likely to be damaged during PCB assembly and transportation. Good thermal stability ensures the inductor maintains stable performance under reflow soldering high-temperature processes and long-term operating temperature rise, adapting to the harsh environmental requirements of automotive electronics and industrial equipment.

Q: How to apply for samples? What is the lead time?

A: You can submit a sample application through our website or email. Please provide your company information and target model. Samples are free of charge and will be shipped within 3-5 working days. Mass order lead time is generally 2-8 weeks.
