Product Description
Product Overview
The ZEMS0850 series is an integral molding power inductor featuring a thin design with low RDC and ultra-high current capability. It offers magnetic shielding for strong anti-electromagnetic interference, making it suitable for high-density installations. Its composite structure provides high reliability, excellent vibration resistance, and ultra-low buzz noise. Designed with low-loss alloy powder, it boasts low impedance, small parasitic capacitance, high efficiency, and reduced winding and core eddy-current loss. It supports frequencies up to 3MHz and has an absolute maximum voltage of 30VDC, complying with RoHS, Halogen Free, and REACH standards.
