jb What is The Difference Between Polyester, Polypropylene?

Polyester films, are clearer and a higher quality than lower grade films, which tend to be foggy. Premium films also endure extreme environments and severe stress conditions more favorably. Films with higher polyester content are more rigid and feel thicker than films with more adhesive content.

Polypropylene film is softer than polyester, but still has excellent clarity. These films have strong chemical resistence, good color stability over printed sheets, and good elasticity which allows the film to lay extremely flat. Due to its softness and flatness, polypropylene films are most often used in single-sided laminating.



X电容是跨接在电力线两线 (L-N) 之间的电容,一般选用金属化薄膜电容;Y电容是分别跨接在电力线两线和地之间 (L-E, N-E) 的电容,一般是成对出现。

jb Plastic Film Capacitor—Dielectric Types

Film Capacitors are Non polarized, and may be used in AC or DC circuits.
Typical values range form 1000pF to 1uF for Polyerster Film, and 0.01uF to 18uF for Metallized Film capacitors. Standard Film Capacitor values change in multiples of 10, 12, 15, 18, 22, 27, 33, 39, 47, 56, 68, 82.

Normal Temperature Coefficient [TC] for Film Capacitors is +7%.

  • Mylar: has a wide temperature change of 20% over -55 to +125°C. Moisture absorption is half that of paper.
    Mylar is the same as polyester. The term Mylar is a trade name.
  • Polycarbonate: Out performs Mylar in all areas. Low Power factor, works best with AC. Polycarbonate has a low temperature drift (graph below), dissipation factor, and dielectric absorption. Use polyphenylene sulfide as a possible replacement.
  • Polyester: Replaces paper for many applications, and smaller in size. Polyester does not have the moisture problem that paper does, but does have a worse tolerance, at 20% ~ over -55 to +125°C. May also be called PETE, or PETP. The Polyester Dielectric has an Absorption of around 0.20%.
  • Polypropylene: It has negative temperature coefficient.
  • Polysulfone: Has a very high operating temperature of +170°C.
  • Polystyrene: Will only work to +65°C. It has a flat to negative temperature coefficient.
  • Teflon: Has a very high operating temperature of +170°C.

jb Told You Capacitors Case Types - Feed Through

Round Feed Through capacitors, in a skin tight plastic wrap with solderable ends (Style Q). The hole in the center of the capacitor is either a Teflon Tube, Paper Tube or Phenolic Tube ranging in sizes from just a wire to a large threaded stud to fit through. The majority of Feed Throughs are custom made to exact customer requirements. They are very popular in filter applications.

Half-life of a Capacitor

When a capacitor discharges its charge throught a resistor, the charge of the capacitor decreases with time. The decreasing charge follows an exponential decay curve.
