Hi I need a datasheet or place where I can source this burned out component on this R/C receiver. I ran a few searches for E3SG which seems to be the lettering on the component. But I came up with nothing. Maybe somebody here can steer me in the right direction. I'm guessing something to do with power regulation based on it's location. Just a guess. It offered up it's sacred smoke when my son plugged power into it. I suspect in reverse polarity although that should not have fried it.

The similar component to the right appears to be a F56A assuming a similar format your part could be E35G or due to the damage anything similar such as E35C or even F35C or G.
However my quick search did not reveal anything for any combination! But it is worth examining the part more closely. Also see if you can identify the manufacturers logo as that may help narrow down the search.
Sorry not to be able to provide the answer.

What RC receiver is it?
I doubt a schematic is available but there are a few on here that have RC as a hobby and may have one to check against.

Hello,

The only one I could find is the E3S:
E3S
XC6121A524MR-G
Torex Semiconductor
SOT-25
Voltage detector IC
2.4V±2%, -Reset ODO, +WDEN, Wt=400ms, Rt=3.13ms

Hi MicroMe The receiver is a redcon FT8rsb 2.4Gh Fasst 8ch.

Thanks for looking

2.4 does not sound right though onless there is some kind of a regulator before it. These receivers are meant to run on3.7 - 7.4V. Or am I wrong? Would a better picture help? I had better lighting today. 20210106_132505_HDR.jpg

It's an elcheapo $30.00 receiver.

Flown all kinds of aircraft in the last 60 years and I tend to shy away from anything that would create a weak link in the rc.

Aircraft are usually worth many times that of the dodgy part.

Not only that, but it puts others at the flight line in danger.

2.4 is 2.4GHz the frequency of operation, NOT voltage of the circuit
