I did a big mistake and damage an electronic coil in my PCB. The only information I did have is the coil itself! There are two identical coil in it.

This is my PCB. It is the [UCD-210M][1].

This is the broke coil

And this is the another good one in PCB.

So, what you can see is the three colors (clockwise):

 - Red
 - Violet
 - Yellow

[This page show how to identify this colors.][6] But it don't show the value of every color, maybe for every series, it change the value. I don't know what is the 1st or 2nd color dots, so I have this:

 - **1st (Yellow) - 2nd (Violet) - 3rd (red)**

Luckily it has this exact configuration, so it give 4700 nH

 - **1st (Violet) - 2nd (Yellow) - 3rd (red)**

It don't show the values…


----------


**Edit…**

The manufacture finally answer the mail. It is a coil of 4.7 µH. He don't give any other detail. 

Everyone was correct. But… The second problem: can any 4.7 µH coil work for it? The size of my coil is: 2.63mm x 2.35mm (I measure it with a digital [calipers][7]). So, with this size, I get [this list][8]. 

I am really afraid about it because all other electronic details. No model look like visually equal to mine. The best option in this list is the [0603PS-472KLB][9] because it size. But if I buy it, will be a trial and error…

So the question is still the same:


----------


Because I have a good one, I can use some tool to measure its value and electric details. What tools is it?

And how can I identify the exactly manufacture of this piece? If I use a generic one, can it cause problem? Maybe I can get this piece from another device, what kind of device use the same coil?
