Sumida High current SMD type Inductor for Automotive applications

5.7.2017
Reading Time: 10 mins read
A A

source: Sumida news

This SMD power inductor series is wound by flat wire and assembled with a Mn-Zn ferrite core. The L values range (lower side) of the existing CDEP15D90/T150 and newly developed 13mm sq. CDEP13D76/T150 was expanded. To meet the high power handling and high insulation voltage demand for automotive applications, the CDEPxxDxx/T150 series which would correspond to high insulation voltage (DC120V) was developed.

※ 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).

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.

Production

CDEP13D76/T150:  in July 2017
CDEP15D90/T150:  in series production
(Note: Though all samples are available now, series production for below 4.7uH L values parts for both types will be launched the series production in Q4 2017.)
