So I've been trying to track down the right capacitor to solder into my mass air flow sensor, in an attempt to fix my stupid van...
Does anyone know what the difference is between, a tantalum capacitor, and an electrolytic capacitor?
Apparently, electrolytic capacitors are the only ones that exist within a 100 mile radius of my house...
...Will it work? |

I've read in here of guys using an electrolytic instead of a tantalum capacitor successfully. Electrically they are very similar- the differences don't bear discussion in this forum. Mechanically they are quite different. The electrolytic is a wrapped foil and dielectric (insulator of identifiable electrical properties) slipped into an aluminum can. They don't do so well in higher heat and vibration environments. You should see the max permissible temperature marked on the can's covering. Exceeding, or even operating near, this temp rating will rapidly affect the health of the component.
Tantalum caps, on the other hand are monolythic, and have a dipped or molded coating. They are much better suited to temps above 85 degrees C, and harsh (mechanical) shock and vibration applications.
You will find them easily at online vendors such as Digi-Key, Mouser, Jameco, and Newark. PM me if you need help finding a part number. I could use one too- maybe we can figure something out.

| Ah, I see. Well, I went ahead and soldered in the electrolytic cap. that I picked up this afternoon, and the van ran like a champ, during test runs... However, I wouldn't mind changing it out for a tantalum one, just for peace of mind. |
