Hello everyone,

In the photo, you can see the flight controller (FC) of my drone, which is a GEP-F7 AIO 45A. I've encountered an issue with one of the capacitors on the back; it appears to be fried and damaged. The problematic capacitor is circled in red.

I need help identifying the type of capacitor used so I can purchase a replacement. Is there a method to determine the exact type and specifications of this capacitor? I believe it might be an SMD capacitor, but I'm not sure and have little experience with capacitors on PCBs.

Any advice on how to identify and replace this capacitor, i Would be really greatful.

Thanks!

 

I would replace it with a 0.1 μF - 50V ceramic capacitor without thinking twice. Typical 'bypass' use. Or, remove any of the similar others to measure.

Got you thanks .. will buy those

 

What are the markings on the IC beside the capacitor?
Provide a sharp, well focused closeup photo of that IC.

Can you clarify which markings you're referring to? I inspected the IC next to the capacitor with a microscope but didn't see any writing. Could you specify the exact part or location you're talking about? This will help me provide the information you need

 

If they have obliterated the IC markings then we can only guess what they are.

Thanks alot. And what about the dimensions. I measured the dimensions and ive got 1.3 mm x 2.34 mm. But those seems not standard. any idea which one should i get . ( 0603, 0805, 1206, etc.)

Unforutnuately.

 

...And what about the dimensions...

Just any that has the same size should work. Some are taller. There is metric and non-metric dimensions. Obtaining them is easy and abundant and free canibalizing defunct electronic gadgets, desoldering takes skill, color will usually be brown and used in ´bypass' at supply pins of I.C.s

Thank you so much for your help Sir! I really appreciate it. I'm following your instructions and learning a lot in the process.

About the capacitors, I noticed that the ones on my board are brown, but I have some unused yellow capacitors that are the same size. Can I use the yellow capacitors instead of the brown ones, assuming they have the same capacitance and dimensions?

 

Do not remember seen yellow ceramic capacitors other than polarized tantalum, but if "assuming they have the same capacitance and dimensions?" Go ahead, try. I would test the board after removing the visually bad one and the one next to it, then place the new ones. There is a good chance they are not essential for the circuit to work. Did you measure the similar capacitors around if 1μF, 10μF, 100μF or ?
