Sumida has developed a low-profile high current power inductor CDEP15D90/T150 for use in automotive LED headlights. Recently, headlights have been diversified and some of them are equipped with ADB (Adaptive Driving Beam) and AFS (Adaptive Front-lighting System) which requires a higher current more than ever. Complying with the automotive reliability criteria, AEC-Q200, this inductor is so strongly structured that its core and wire could withstand a voltage of up to 120Vdc.
These inductors are offered in standard designs and high-power designs. Typical ratings for the standard designs ranges from; inductance of 4.7uH Â±20%, DCR of 3.5 mOhms Â±20%, saturation currents of 17.0A at 20 degrees C and 11.8A at 150 degrees C for the CDEP15D90T150NP-4R7MC-125; to inductance of 22.0uH Â±20%, DCR of 14.5 mOhms Â±20%, saturation currents of 7.7A at 20 degrees C and 5.3A at 150 degrees C for the CDEP15D90T150NP-220MC-125
Ratings for the high-power series range from; inductance of 4.7uH Â±20%, DCR of 4.9 mOhms Â±20%, saturation currents of 19.2A at 20 degrees C and 13.3A at 150 degrees C for the CDEP15D90T150NP-4R7MC-100; to inductance of 22.0uH Â±20%, DCR of 20.1 mOhms Â±20%, saturation currents of 8.8A at 20 degrees C and 6.0A at 150 degrees C for the CDEP15D90T150NP-220MC-100
