※ 1 Measuring frequency at 100kHz 0.1V

※ 2 Saturation current: This indicates the actual value of D.C. current when the inductance becomes 30% lower than its

nominal value.

※ 3 Temperature rise current: The actual value of D.C. current when the temperature of coil becomes △T=40°C

(Ta=20°C).

※ 4 Measurement condition: Irms testing was performed by a product in 25°C ambient.

※ 5 Measurement condition: Irms testing was performed on copper traces in 25°C ambient.

※ 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.
