Substitute For Ceramic Capacitor

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

Substitute for ceramic capacitor.

The mod i am doing they call it the voodoo chile mod says to substitute the 470pf cap for a 47 uf cap. 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. Ceramic capacitor definition a ceramic capacitor is a capacitor which uses a ceramic material as the dielectric. Class 1 and class 2.

Film capacitors cannot be replaced with ceramic or mica capacitors if used for analog signal processing. In the 21st century the international electrotechnical commission iec currently separates ceramic capacitors into two classes. I meant 47 uf. The two most common types are multi layer ceramic capacitors and ceramic disc capacitors.

Per the iec guidelines. Finally i could put several smaller high voltage ceramic capacitors in parallel so that the load is split over many. You are also right the original part is 470 pf. Yes you are right i made a mistake.

Ideally though again depending on the application use a replacement as a temp. The original part is ceramic non polarized. There are two classes of ceramic capacitors available today. I went ahead and ordered the 47 uf stacked metal film caps.

However mica capacitors can be replaced with ceramic capacitors in general. Polystyrene capacitors are generally unavailable nowadays.
