Power Inductor: CDRH40D28/T125

May 13th 2016

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.

 Key Features

  • Size: 4.5 x 4.5 x H3.0 mm (Max.)
  • Product Weight: 0.13 g (ref.)
  • Operating Temperature Range: -40°C to +125°C
    (Including coil's self temperature rise)

Applications

TVs, video players, AV, Industrial and automotive equipment.

※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℃).
