Wire Wound SMD Power Inductors for Automotive
AMWPB Series
Overview
The AMWPB series of power inductors are assembled magnetic shielded inductors developed by
Sunlord using the accumulated manufacturing process experience and material technology, combined
with the BASE card wire laser welding process. This series of products mainly have 6045 size and 7045
size, rich inductance value, and compared with traditional winding inductors, it has high reliability, can
withstand harsh environment such as vehicles, and the product's operating temperature range reaches
-55°C ~ + 150° C.
Background
Power inductors act in power circuits such as DC-DC converters and have the ability to accumulate
energy through self-inductance. In DC-DC converters, the voltage in the circuit is converted by
cooperating with switching devices. With the development of automotive electronics, the demand for
high-performance DC-DC converters continues to increase, and power inductors are important
components that influence the performance of their DC-DC conversion modules.
Sunlord Automotive Electronics launched the AMWPB series of products, focusing on improving the
electrical performance and reliability of the products, and realizing high-performance products for various
in-vehicle applications such as in-vehicle infotainment systems, LED lights, and airbags.
