Product Description
SMMS Series Ultra-high Current SMT Power Inductors
The SMMS Series are thin, molded SMT power inductors designed for ultra-high current applications. They feature magnetic shielding for strong anti-electromagnetic interference, making them suitable for high-density installations. The integral construction provides high reliability and excellent vibration resistance, while the composite structure ensures ultra-low buzz noise. Utilizing low-loss alloy powder die-casting, these inductors offer low impedance, small parasitic capacitance, and high efficiency, reducing winding DC resistance and core eddy-current loss. They operate at frequencies up to 3MHz and have an absolute maximum voltage of 30VDC, complying with RoHS, Halogen Free, and REACH standards.
Features:
- Thin design with low DC resistance and ultra-high current capability.
- Magnetic shielding for strong anti-electromagnetic interference, suitable for high-density installation.
- High reliability and excellent vibration resistance due to integral construction.
- Ultra-low buzz noise due to composite construction.
- Low impedance and small parasitic capacitance from die-casting with low-loss alloy powder.
- High efficiency with low winding DC resistance and low core eddy-current loss.
- Frequency up to 3MHz.
