SHENZHEN SHUNXIANGNUO ELECTRONICS CO., LTD. - SMMS1040 Series Molding SMD Power Inductors
The SMMS1040 Series ultra-high current SMD power inductors are designed for high-density installation and offer a thin profile with low DC resistance and ultra-high current capabilities. Featuring magnetic shielding for strong anti-electromagnetic interference, these inductors are built with an integral construction for high reliability and excellent vibration resistance. They utilize a composite structure for ultra-low buzz noise and a low-loss alloy powder for die-casting, resulting in low impedance and small parasitic capacitance. These inductors achieve high efficiency due to low winding DC resistance and reduced core eddy-current loss, operating at frequencies up to 3MHz with a maximum insulation voltage of 30VDC. They are RoHS, Halogen Free, and REACH compliant.
