Discharge static electricity before handling this coil. Take the static electricity measures to prevent deterioration of electric characteristic For only CDMT40D20HF-4R7NC will be started mass production from March 2016. Others are available for mass production. Note: This datasheet might be slightly modified without notice in order to improve the quality and reliability of the product.
