Electrolytic capacitor identification

[David Rickman]

This capacitor in my Garmin 551dv fishfinder blew and I need help identifying it and possibly where to get a new one.

Try visiting the links on this Google results page. Possibly a 220 μF, 50 V, electrolytic capacitor.

While I have not identified the exact cap from my previous searches I agree with @hevans1944

405 is likely a dat code 05 month of 2004
220 is likely 220uF
50Z is going to be 50volts and then Z will either be a tolerance or series indicator

Ok thanks guys

I'd be more concerned for WHY that capacitor blew up in the way it did......

 

[David Rickman]

While I dont disagree with you, i have no way of finding that out. I want to believe it could have happened due excessive heat, ut is in a black case in direct sunlight or it could jave happened when i had to jumpstart my boat. But for the 88 cents plus shipping i will gladly replace it and see.

Can you show where, on the unit, the capacitor came from?

 

[David Rickman]

Yes, it goes right near where the power cable connects, right where im pointing with the screwdriver, you can see the burn mark on the casing too.

Is the pic uploading?

The adjacent inductor points to an SMPS-derived supply onboard - quite common - and blown capacitors are a definite problem in some designs so your fault could just be pertinent to the design but the severity of the failure is quite surprising.

If/when you change it I'd recommend powering up with the lid off and letting it run for a good few hours to make sure there isn't something else amiss.

Ok thanks, the new one should arrive this week, ill take your advice with it.
