A fully automated winding, soldering, testing, and packing machine produces this miniature wire-wound SMD power inductor. 100% check is performed before each shipment, which includes testing for characteristic inductance value, DC resistance, Isat current, and layer isolation.
Zxcompo Leadtime:
Zxcompo’s standard delivery time is 1~2 weeks, and fast delivery plans within 3 days are available in urgent cases. This offers customers reliable quality and stable (short) delivery dates (in urgent cases, the delivery date could be 1 day 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.
