Polyester film capacitors are film capacitors using a dielectric made of the thermoplastic polar polymer material polyethylene terephthalate (PET). We're JYH HSU(JEC) Electronics Ltd (or Dongguan Zhixu Electronic Co., Ltd.), an electronic components manufacturer. You may google search "JYH HSU" to find our official website.
A metal film capacitor is an electrical part that holds energy electrostatically inside of an electric field. The capacitor has a dielectric which separates two electrical parts which are made out of thin film.

Last time I looked there are no 47nF polarized capacitors. The value is too small to make practically.
Fire alarm system may be having some electronic devices and cards, in which some capacitors are used. Capacitors are part of any electronic cards.
PF (polyester film) capacitors and UF (film capacitors using an unspecified type of plastic, often polystyrene) differ primarily in their dielectric materials and applications. PF capacitors are typically more affordable and widely used in general-purpose applications due to their stability and reliability. UF capacitors, on the other hand, often provide better performance characteristics, such as lower distortion and higher frequency response, making them suitable for audio and precision circuits. Additionally, PF capacitors generally have a wider voltage rating compared to UF capacitors.
The polyester will shrink.
No. Polyester is a nice fiber. Some people like it some don't. I personally find it nice.
Some capacitors have terminals as they are polarized but some have not as they are not polarized. you can easily identify a polarized capacitor as it has + or - terminal indication marked.
Some capacitors are polarity sensitive; some are not. It depends on the design. Electrolytic capacitors, for instance, are polarity sensitive, while ceramic disc capacitors are not. You can generally tell, if the capacitor is marked with polarity signs, such as + and -, if it is or not.
Polyester taffeta is generally smoother and more tightly woven, making it suitable for applications like linings and lightweight garments, but it may not be as durable as polyester ripstop. Polyester ripstop features a grid pattern that reinforces the fabric, enhancing its tear resistance and overall strength. Therefore, while both fabrics have their uses, polyester ripstop is typically stronger and more resistant to wear and tear compared to polyester taffeta.
