Audited Supplier The SMP(Molding Chock) inductor comprises a seat body and a winding body, as the seat system is formed by embedding the winding body in the metal magnetic powder, and the SMD pin is a lead-out pin of the winding body and is directly formed on the surface of the seat body, The utility model has higher inductance and less leakage inductance compared with the traditional inductor.
Our main products:SMP0420 series,SMP0520 series,SMP0530 series,SMP0624 series,SMP0630,series,SMP1040 series,SMP1050 series,SMP1250 series, SMP1265 series,SMP1770 series.
Compared with other inductors,The SMP' s Features:
★The same product size has lower DCR;
★the inductance value is reduced smoothly with the sensitive current;
*Up to 5MHz with Frequency;
★The molding structure can avoid noise;
★The molding structure can effectively reduce the electromagnetic interference;
*lead-free product,Comply with RoHS;
★It is suitable for vehicles, medical,erospace, submarine and other industries with high and reliable requirements.
