Product Overview
The CIB/CIM21 Series are monolithic inorganic material chip beads designed for EMI suppression. They feature a closed magnetic circuit configuration, ensuring no crosstalk and suitability for high-density PCBs. These components are ideal for automatic mounting with no directionality and offer excellent solderability and high heat resistance for both flow and reflow soldering. Applications include high-frequency EMI prevention in computers, printers, VCRs, TVs, and mobile phones.
