SMMS Series Ultra-high Current SMT Power Inductors
The SMMS Series offers thin, molded SMT power inductors designed for ultra-high current applications. These magnetic shielding type inductors provide strong anti-electromagnetic interference, making them suitable for high-density installations. They feature high reliability with excellent vibration resistance due to an integral construction, ultra-low buzz noise from a composite structure, and low impedance with small parasitic capacitance achieved through die-casting with low loss alloy powder. These inductors offer high efficiency by reducing winding DC resistance and core eddy-current loss, with frequencies up to 3MHz and an absolute maximum voltage of 30VDC. They are RoHS, Halogen Free, and REACH compliant.
