WHAT BRAND OF CAPACITOR DO YOU CARRY ???

[AIRCON8]

who - your oncologist

why - prolonged exposure often result in cancers of various types

[AIRCON8]

i guess PCB oil just don't work well as main component for capacitors.

[EugeneTheJeep]

PCB capacitors were the best, they were self healing.

so why Amrad las so long ??

Mars, made in the USA.

Correction: Mars are assembled in the USA. Titan HD and Amrad made in the USA not just assembled in the USA.

Mars uses BMI.

i'm wondering if Titan HD are BMI too

[AIRCON8]

Anyone know who make TITAN HD capacitors ??

This is a question asked by many beginners. I will give you a simple answer to this question without going into all the details. After reading this, my goal is that you should be able to go and find the capacitor you need right away.

I have also written about how to choose capacitor values that I recommend you check out.

Different capacitor types

Polarization
First of all, we boil it down to two capacitor types:

Polarized capacitor
Non-polarized capacitor
The difference between a polarized capacitor and a non-polarized capacitor is that the polarized capacitor has a positive and a negative side. So it must be placed with the positive pin where the most positive voltage is. You can place the non-polarized capacitor in any way you want.

Do you need a polarized capacitor? Or a non-polarized capacitor? To figure this out, look at you schematic diagram. What capacitor symbol is used?

These are non-polarized capacitors:

Schematic Symbols Capacitor US Style
These are polarized capacitors:


Polarized capacitors
If you need a polarized capacitor, you need something called an “electrolytic” capacitor. There are two types of electrolytic capacitors:

Aluminum
Tantalum
Aluminum
The most common is the aluminum capacitors. It is also the cheapest of the two. Aluminum caps usually come as through-hole components. But you can find some surface mount versions of it as well. Choose aluminum caps unless you have any special requirements.

Tantalum
If you need a smaller and more durable capacitor, you should choose the tantalum type.

Tantalum caps are available in small surface mount packages. They can work in a wide temperature range. Note that some tantalum caps come in non-polarized version also.

Tantalum capacitors



Non-polarized capacitors
If you need a non-polarized capacitor, look for either a ceramic or a film capacitor.

Ceramic caps are small and cheap. It’s the most common choice for non-polarized capacitors. They are often used as decoupling capacitors.

Ceramic capacitors

If you have any special requirements like low tolerance, high reliability or a capacitor that is able to operate under high temperatures, then choose a film capacitor. It is much better for this.

Film caps can be made of polystyrene, polycarbonate or Teflon. They each have their own properties, but that is out of the scope of this page.

I didn't ask for anything, and i'm not a beginner !!

That's funny. I just read the entire thread and you asked the same question about 5 times and multiple other questions. To make a statement that you didn't ask for anything is crazy.

[AIRCON8]

funny

[mialex]

I am aware that this one is an old thread. but...

Almost 5 years ago, I replaced the original 19 yo GE Capactor in my unit, because it was reading a lil under. I used the Genteq with the same part number as the GE capacitor. Well, the replacement failed after 1769 days, which would roughly come up to 15,000 hours of actual use. The box on the Genteq indicated 60,000 hour reliability.... yeah right.

After 4 years the top of the Genteq was all rusty. I cleaned it and applied a clear coat to protect it.

To get the unit running I used the 19 yo capacitor which I had kept. Now I am trying to find a better replacement

[Snapperhead]

Capacitors are designed to fail now

Get used to it

Trade Pro , Amrad , are good caps , but dont expect any where near 19 years

[VTP99]

Go back to PCB's 😉

All manufacturers followed with the possible exception of manufacturers of things like the Mars rovers and space station component manufacturers.

[mialex]

Thanks for the your suggestions.

Amrad did not have the capacitance I needed in the size that fits nicely in the unit.

I decided to try BMI capacitors. Their literature is excellent, and they supposedly meet EIA546A.
