Can anyone ID this capacitor please? Linked to....

[Safety First]

If anyone can help with this, we'll save a packet and get this juicer working again. I hoped this would be a simple replacement/switch over job...

Thanks for taking the time.

7uf 450v capacitor any of these will do.

 

[bernardgreen]

From the part number HSC 45M070U SH I would hazard a guess that it is a 7 micro Farad capacitor at 450 V AC rating. ( NOT 450 V DC )

The label on the motor confirms 7 micrro Farad

Which is about the correct value for a motor run capacitor.

These are 6.8 microFarad which will work just as well.

Thanks both. For the cost of a punt on one of these v's replacement item, it's a no brainer to have a go at.... even if it pops the next one too.
Anyone know why it might have happened? Do cap's just die? Juicer is about 10 years old and had just come out from a very long non-use period.
As I say in the linked to listing. With the blown capacitor in place again, the motor runs still. Just not with any grunt.

Am watching vids about what cap's are and how they work...

Yes !

Yes !

Kind Regards, John

Good!

It's all a bit amateur ish, but given that they (caps) might just fail, I can go ahead and buy a replacement instead of having to find a/the fault that killed the cap'.

Thinking of getting this one..

Just not 100% on whether its 450v, as it says 450v in one place and 400 further down...

10,000hrs life at 450v
30,000hrs life at 400v
Either way that's one hellova lot of juice making

Ah! I see!
Thanks for clarifying that.
No chance we got that from the first one. I have read they can often 'go'/short after a very long spell dormant, but these were the aluminum cased types filled with oil.
Where can you get them from, other than online. Put feelers out for knackered tumble driers locally, just in case...
Getting a bit silly trying to save a few quid.

Tumble drier is your best bet. Washing machines generally use brushed motors. An old fluorescent light might also be a source - used for PF correction in them. Values will probably be wrong but 'near enough' might be exactly that.

Would advise buying a brand new capacitor of the correct value, the wrong value may cause the motor to run hot or weak (or both!). Unless you have one laying around to try, probably not worth messing about trying to get one from an old tumble dryer or the likes. There's one slightly cheaper here: https://www.ebay.co.uk/itm//163293047485
