Sumida has developed a new type of power inductor CDRH40D28/T125 through the use of a new material which allows for the product to be used in high temperature applications. The product has been improved from an operating temperature range of (-40°C – 105°C) to (-40°C – 125°C). This inductor is a surface mount ferrite inductor. It can be used for automotive and industrial as well as consumer applications.

※1 Measuring frequency inductance at 100kHz,1V.
※2 Saturation current: This indicates the value of D.C. current when the inductance becomes 35% lower than its nominal value.
※3 Temperature rise current: The actual value of D.C. current when the temperature of coil becomes △T=40℃ (Ta＝20℃).
