The polypropylene is sometimes used when a higher tolerance is necessary than polyester capacitors offer. As the name implies, this capacitor uses a polypropylene film for the dielectric. One of the advantages of the capacitor is that there is very little change of capacitance with time and voltage applied. They are also used for low frequencies, with 100 kHz or so being the upper limit. They are generally only available as leaded electronics components.

Such as our polypropylene film capacitors , it has three features:

1. Comparatively small size saves space of print circuit board.

2. Temperature dependence indicates characteristic of negative.

3. Dissipation Factor is normally low and temperature dependence of capacitance is linear.
