SM Series SMD Unshielded Power Inductors | SM3521

Remark: Design as Customer’s request specification.

SHAPE AND DIMENSIONS

This miniature wirewound SMD power inductor produce by fully automated winding / soldering / testing and packing machine. 100% check before each shipment, the testing included the characteristic inductance value, DC resistance, Isat current and layer isolation.

Zxcompo Leadtime:
Zxcompo’s standard delivery time is 1~2 weeks, and in urgent cases, fast delivery plans are available. For specific product ranges, we can dispatch goods within 10 or 20 working days. This offer customer reliable quality and stable (short) delivery date (urgent case, the delivery date could be 1 weeks only)

Zxcompo Customization:
In addition to the standard features of our family of specifications, Zxcompo offers low minimum order quantities (MOQs), tighter tolerances, and custom products for different inductance and frequency applications. With our team of engineers’ deep background in the ferrite powder field, we can modify the core powder to design and produce the most suitable product to meet our customers’ applications.
Whether your design targets power supplies, filtering circuits, or specialized applications, our custom semi-shielded SMD inductors can be meticulously optimized to excel within your precise field of application. If your PCB layout calls for a particular size to fit seamlessly, rest assured, we’ve got you covered. Our expertise allows us to customize the dimensions, ensuring a perfect integration with your design.
