Try www.newarkinone.com look under passive componets

What kind of capacitors and for what purpse?

 

[Pattylucylaura]

for a 175w metal halide ballast

Do you have one to replace? If so the first place to check is the ballast OEM. IF they don't have it, try IceCap (I think they used to repair ballasts and have a decent stock). McMaster is also a good place to look.

The electronics supply houses (Allied, digikey, Farnell, Newark, etc) will have them, but they will be pricey for what you are looking for.

If you post the specs, we can help you find one (hopefully for a few bucks). You need to at leat match the voltage rating on the cap, but higher is fine. The cpacitance rating should be within 10% or so of what you are replacing. The sad joke is most cheap caps that are found in these units are 20% tolerance (and some as bad as 50%).

Agreed , there is a voltage rating along with the microfared rating on the Cap.

I had a hell of a time trying to replace some cap's on a m57 ballast. I ordered several from some of the supply houses , using the exact info on the cap, and got back tiny pcb board style capacitors, not oil filled or similar.

I called a shop local and they had one, and wanted $40 for it. PFFT.

I ended up contacting advanced and they sent me replacements for free.

Might be something worth looking into.

good luck.

It is 10uf 400VAC I found this one will it work? Newark

 

[Pattylucylaura]

Oh yeah I need to replace mine.

 

[nebraskareef]

yup, thats an oil filled cap. Thats what mine use.

you should be fine.

 

[Pattylucylaura]

Anyone else I want to be positive before I order. Not that I doubt you I want to be 110% I think it will work though and you agree I may just order it.

 

[mg426]

Looks good to me too.

 

[Pattylucylaura]

ok will this one work Ebay mine is10uf 400vac this one is only 370vac will this work

 

[nebraskareef]

I'm not an expert at electronics, but I would never imagine using anything that wasn't atleast in OEM specs.

It's not worth saving a few bucks.

 

[Pattylucylaura]

what about this one ebay I think this is what I need right 10uf 440Vac.

best to order from an reputable dealer. all electronic componets are "not" created equal. cheap componets = subpar performance = reduced longevity. this is a huge subjective matter that depends on many parameters including the type of electronic appliance in question. but for a higher end device or someone that wants dependability, ie: hospitals etc... quality should win out over cost on individual componets. this is not a user opinion, just a fact.

Patty, I think the last poster was very clear. Go buy the cheaper eBay one, and risk a premature failure due to low quality. Worst case, you end up having to repair it again, or maybe it burns the place down.

You're in the wrong hobby if saving $2.00 means taking such a risk.
