Replace ceramic capacitor with film. I bought them to replace the tantalum capacitor that goes with the dspic chip they dont explode. This film is made extremely thin using a sophisticated film drawing process. Replace electrolytic for ceramic caps page 1. 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. 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 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.

Metalized polyester film capacitors are cheaper but their electrical characteristics aren t quite as good. You may as well go with the common yellow metalized polypropylene film capacitors and be done with it. Film capacitors are capacitors which use a thin plastic film as the dielectric. I also going to try ebay for 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. 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.
