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]. ![PCB][2] This is the broke coil ![broke coil][3] And this is the another good one in PCB. ![good coil][4] [Click this link][5] to see more images. 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… Because I have a good one, I can use some tool to measure its value. 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?
