Can some one identify this Capacitor and tell me the use of such capacitors?


The Diagram shows a capacitor (orange-brown color) which reads 1.1k and 250V
now it does not make sense that its value is 1.1kF . some people say that it may be 1.1k x 1pF = 1.1nF . but if its like this then why not just write 1.1nF.

and what is the type of the capacitor i guess it is metalized poly-propylene film capacitor is this true ?

also that what is the application of such types of capacitors like electrolytic are used generally in power supplies etc?

All Right people Thanks to iceng i got the answer .it is

if a cap has a code 224k600V 9644

Manufacturer Coding:
224= capacitance in pico farads - first two digits are significant digits, third digit is the number of digits that follow (i.e: 22 + 0000 = 220,000pF = 0.22µF in this case)
K = tolerance,
F = ±1%, J = ±5%, K = ±10%, etc.
600V = voltage rating (600 volts in this case)
9644 = date code (44th week of 1996 in this case)

here is the link if u want to calculate one or see in detail
and one thing more it is actually Orange drop capacitor

I don't believe that it is a poly-propylene cap
Poly-propylene caps are much lower voltage and very stable units.
And different construction from what is seen here...

This is a plain orange drop film capacitor.

I never did comprehend the value markings and prefer to measure the
capacitance value myself before using the component.

Poly-propylene caps are used in timing critical applications where stable cap
value is essential like ADConversion.

An orange drop film capacitor is more stable then a disc capacitor and
finds use in snubbing circuits used to reduce the rate of voltage rise per time
that a Triac, SCR or four layer diode would not want to experience failure...

Switching inverters / converters also like to use plain film capacitors..

It might be a suppressor too, in which case its a cap and resistor in series.

The notation is standard.
