Hello,

Can i replace polypropylene film capacitor (105K - 400 V) with any other type of caps, my fan doesn't work and i can't find a new cap.

THANKS.

 

Hello,

THANKS.

Look for a "1 uF", "400 V AC" capacitor as a replacement. A slightly higher capacitance value does no harm. But it Has To Be An AC Capacitor - non polarized.

 

I spent weeks searching for it all i can find is ceramic and electrolytic caps, so i'm trying to replace it with another type(i'm a civil engineer)

 

First off, what makes you think that your fan has a bad capacitor? That IS a failure point, but not a very common on.

 

If the capacitor is of Chinese origin, there is a good possibility that it is the cap. A common failure point.
Try a local motor rewinder or search for 'AC motor run capacitor'
There are rafts of them on ebay for a $1.00 but unfortunately most Asian origin.
Is your supply 120vac or 230v?
Max.

Which country are you in? Here, in India, any electrical shop would have these.

Mouser lists dozens of choices for 1uF 400VAC:

Many of those are DC rated only and do not give any AC spec
e.g. MKS4S041007H00KSSD
App Requires motor run rated.

The first datasheet I looked at, with a 630VDC rating, indicated the maximum AC voltage was 400.
