NOTE
Please note that when using the product for automotive while applying current with audio-frequency (AF) signals may result 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 may amplify depending on the coil mount area on the PCB.
