Replace Ceramic Capacitor With Film

To construct a film capacitor either 1 two metal films with an intermediate film or 2 films of dielectric on which a metal layer is vapor deposited are wound.

Replace ceramic capacitor with film.

Ideally though again depending on the application use a replacement as a temp. You may as well go with the common yellow metalized polypropylene film capacitors and be done with it. Eevblog electronics community forum. Film capacitors are capacitors which use a thin plastic film as the dielectric.

What are film capacitors. There may be some who tell you that you need to purchase a particular variety of capacitor for its particular audio or sonic qualities. I also going to try ebay for film capacitors. Hi i am fairly new to electronics and so i hope this isnt a stupid question but i was wondering what the difference would be using a ceramic capacitor over.

Small value ceramic capacitors are generally used for electrical coupling or decoupling of intermediate circuit stages and plastic or metal film make suitable replacements. A free open forum for electronics enthusiasts professionals. If i m taking the engine out of my car at 90 000 miles and the clutch isn t quite worn out yet i m still replacing the damn clutch because it s easier to do it at that point than at some. A non polar capacitor film and ceramic can be operated with both dc and ac voltage while a polar capacitor electrolytic and super can be operated with dc voltage only.

Metalized polyester film capacitors are cheaper but their electrical characteristics aren t quite as good. A ceramic capacitor is a fixed value capacitor where the ceramic material acts as the dielectric it is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes the composition of the ceramic material defines the electrical behavior and therefore applications.
