Product Description
Product Overview
The ZEMS0850 series are integral molded power inductors designed for high-density installation. They feature low DC resistance, ultra-high current capability, and magnetic shielding for strong anti-electromagnetic interference. These inductors offer high reliability, excellent vibration resistance, ultra-low buzz noise, and high efficiency due to their composite construction and low-loss alloy powder die-casting.
