Not 850v but I’ll try these caps…about $2.60 each

Capacitor 10Pcs/Lot SMD Ceramic Capacitor 1812 224K 0.22UF 220NF 100V 630V X7R 10% Non-Polar Capacitor high Voltage C4532X7T2J224K200KC (Capacitance : 630V) : Amazon.ca: Industrial & Scientific

with primary kick back at less than 300v  hopefully these will hold up 🙂

waiting for the postman….

You must have bought the last of them…they show not available anymore. I looked the other day after reading Bill Mohat’s article on condensers and they also are not available.

[JACQUES]

lets put it this way… they have not reached me yet….:-)

one roll of noise insulating foam took +3 months to get to me  at least Amazon credited my initial purchase 🙂

Digakey should have what you want. And they will talk to you if you need help.  I use 600+volt 0.15-0.18 UF on my old merc’s and have no problem

these were just 2,60 cdn  so I jumped on it

I play around repairing vintage audio gear during the winter months and am having trouble finding certain semiconductors, caps,  and resistors right now which are normally available. Digi-Key and Mouser have extremely long wait times for some of them and it could be due to covid.  Lots of things we take for granted are in short supply right now.

About those caps, you think ceramics will work OK and hold up?  You might want to try and find the data sheets for them and compare them to film caps which we know are reliable in magneto applications.

Well  in light of M.Mohat’s article the X7R type ceramics are  compact and  work very well .   I have the other types   round yellow ones about 1 inch  630v   and… the little square ones (brown)  630 also ..

OK, but it’s kind of like buying tires for your vehicle.  There are snow tires, summer tires, M+S tires, All Terrain tires etc.  They are all the same size and will fit the rims, but are meant for different applications.

agree on tires… for caps I am strickly relying on the  conclusion of extensive testing and reporting  in mr. Mohat’s article.    Time will tell if I live long enough 🙂

currently   my stack  oldies have been refurbished with regular caps …. so I can’t say how things will go . …no more room to store them 🙁

According to BrightSpark’s website, they have shipped about 3,000 of
these X7R-based condenser replacements, with ZERO failures over a 3 year period. In
addition, they have tested dozens of them on “magneto simulators”, running them 24
hours a day for that entire 3 years….also with no failures. (That’s not long enough to
predict how long their entire service life is going to be in magneto applications, but I’m
guardedly optimistic that they’ll last longer than any mylar film condenser in these
applications!

update:

well  guess I won’t be using any … X7R  caps

 

China tracking says the stuff was handed to me  on Feb 02  ???     and…that ain’t so 🙁

 

Seller notifyed…we shall see if they refund me or reship… if not I’ll try a VISA chargeback
