Replace Ceramic Capacitor With Film

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.

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. Eevblog electronics community forum. What are film capacitors. Small value ceramic capacitors are generally used for electrical coupling or decoupling of intermediate circuit stages and plastic or metal film make suitable replacements.

There may be some who tell you that you need to purchase a particular variety of capacitor for its particular audio or sonic qualities. 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. A free open forum for electronics enthusiasts professionals. Metalized polyester film capacitors are cheaper but their electrical characteristics aren t quite as good.

Film capacitors are capacitors which use a thin plastic film as the dielectric. I bought them to replace the tantalum capacitor that goes with the dspic chip they dont explode. You may as well go with the common yellow metalized polypropylene film capacitors and be done with it. Ideally though again depending on the application use a replacement as a temp.

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.
