Molding SMD Power Inductors - SMS1040 Series
Product Overview
The SMS1040 Series Ultra-high current SMD power inductors from SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. are designed for high-density installations requiring low DC resistance and ultra-high current handling in a thin profile. Featuring magnetic shielding for strong anti-electromagnetic interference, these inductors offer high reliability with an integral construction for excellent vibration resistance. Their composite structure minimizes buzz noise, while the low-loss alloy powder die-casting contributes to low impedance and small parasitic capacitance, ensuring high efficiency. These inductors operate at frequencies up to 3MHz and are RoHS, Halogen Free, and REACH compliant.
