Smd inductor code

[omid_juve]

I have one inductor with these code written on it "3384E01" I measure it , it was around 3.37mH but the precise value is important to know it is for a switch of a car that it will make a specific freq. Together with a capacitor

Hi,

Sorry, I can´t help with the inductor.

When reducing the picture to the essential size with suitable JPG quality it just takes 1/80 of the initial file size.
Some members linve in areas with low internet bandwidth... thus it reducies drastically the time to show the picture.

When you place a ruler next to the inductor we even know it´s measures.

The number on the device says "3384", you measured 3.37mH. I think it's a pretty reasonable to assume it's a 3.38mH inductor. How much more precise do you need?

The IC data sheet states 4.8mH to achieve resonance but it depends on the parallel capacitor of course. It puts 3.38mH in the right 'ball park' range and given the manufacturing and measuring tolerance, seeing 3.37mH doesn't seem unreasonable.
