I bought a small blower a while back & never was able to figure out what capacitor to get for it.
web search returned too technical info for my level


Ametek Rotron propimax 3BL part no 041037 series 763ZH
115 volt ac
60 hz
1 phase
.13 amp
3450 rpm
PH. SEQ

Cap 0.5 (with no u or F) so am I right in assuming it is .5F?
has a small wiring diagram [see photo (fixed type capacitor ?)]

I buy from digikey so if someone can point me to a solution, part no greatly appreciated.
Also which wire connects to black? yel or red?
Thanks in advance

If it was 5F you wouldn't be able to get it into your shop!!
It is most likely 0.5µf
Make sure you get AC motor run rated cap, a oil filled paper is typical type.
You can also get them at a local rewind shop.
The cap goes across RD and BE, whatever they are.

okay, so I go to digikey and search for 'capacitor' too many choices and none say oil filled paper
so I search for 'oil filled paper' - nothing
then I search for 'AC motor run' - returns 'film capacitor' as one choice
filter for 0.5uF
and I get 4 capacitors, all motor run type, but they are rated:
440-700 volt AC and are 2.160" L x 1.310" W x 2.250" H
costing $12-20

really?
the motor is less than 1.25" in diameter & less than 1.75" long
the blower is 3.75" overall diameter
the wires are only 20-24 gauge
Does this blower really need a capacitor that is larger than the motor?
And does it matter which way the capacitor is connected to the red & blue wires?

For a small motor You may get away with metalized polypropylene, for cheaper.
Polarity does not matter.
