Chip Bead (CIB/CIM Series)
CIB, CIM Series are used for EMI suppression filters.These beads suppress EMI noise by increased impedance, especially by increased resistance at noise frequency. CIB series is composed of mono-layer internal conductor that allows low impedance and low DC resistance. CIM Series displays high impedance because it is composed of a multilayered internal conductor and has excellent attenuation characteristics for wide band frequencies
General Features
- Smallest inductors suitable for surface mounting - Perfect shape for automatic mounting, with no directionality - Excellent solderability and high heat resistance for either flow or reflow soldering - Monolithic inorganic material construction for high reliability - Closed magnetic circuit configuration avoids crosstalk and is suitable for high density PCBs.
CIB/CIM Series
Applications
- High frequency EMI prevention application applicable to computers, printers, VCRs, TVs and 9 portable telephones
