Substitute For Ceramic Capacitor

Per the iec guidelines.

Substitute for ceramic capacitor.

I went ahead and ordered the 47 uf stacked metal film caps. The original part is ceramic non polarized. Small value ceramic capacitors are generally used for electrical coupling or decoupling of intermediate circuit stages and plastic or metal film make suitable replacements. Ideally though again depending on the application use a replacement as a temp.

I meant 47 uf. You are also right the original part is 470 pf. Ceramic capacitors were first developed in the 1920s in germany as a substitute for mica dielectrics. The mod i am doing they call it the voodoo chile mod says to substitute the 470pf cap for a 47 uf cap.

The two most common types are multi layer ceramic capacitors and ceramic disc capacitors. In the 21st century the international electrotechnical commission iec currently separates ceramic capacitors into two classes. For example 10 100 pf ceramic capacitors in parallel is much cheaper than 1 1000 pf silver mica capacitor and the ceramic capacitors are rated for 2 kv while the mica is rated for 500 v. Yes you are right i made a mistake.

Ceramic capacitor definition a ceramic capacitor is a capacitor which uses a ceramic material as the dielectric. Finally i could put several smaller high voltage ceramic capacitors in parallel so that the load is split over many. 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. However mica capacitors can be replaced with ceramic capacitors in general.

Film capacitors cannot be replaced with ceramic or mica capacitors if used for analog signal processing. Characteristics precision and tolerances.
