Low-Profile High Current Power Inductor: CDEP15D90/T150
March 14th 2016Sumida 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 absolute Maximum Voltage (across inductor): 200V.
Key Features:
- Size: 16.0 x 16.0 x H10.0 mm Max.
- Product Weight: 7g (ref.)
- Absolute Maximum Voltage (across inductor): 200V
- Operating Temperature Range: -40°C to +150°C
(Including coil's self temperature rise)
Applications
Automotive ECUs and headlights, etc.

*1 Measuring frequency inductance at 100kHz、1V
*2 The saturation current：The value of D.C. current when the inductance decreases to 70% of its initial value.
*3 Temperature rise current：The actual value of D.C. current when the temperature rise is ⊿T=40℃（Ta=20℃）
| * | Please note that when using the product while applying current with audio-frequency (AF) signals may results in audible noises due to magnetostriction. Also, in order to avoid an audible noise problem, operating with non-AF signals would be recommended. The noise amplify depending on the coil mount area on the PCB. |
