Substitute For Ceramic Capacitor

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.

Substitute for ceramic capacitor.

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. Ceramic capacitors were first developed in the 1920s in germany as a substitute for mica dielectrics. Yes you are right i made a mistake. The original part is ceramic non polarized.

Class 1 and class 2. Per the iec guidelines. Polystyrene capacitors are generally unavailable nowadays. Ceramic capacitor definition a ceramic capacitor is a capacitor which uses a ceramic material as the dielectric.

You are also right the original part is 470 pf. Ideally though again depending on the application use a replacement as a temp. Finally i could put several smaller high voltage ceramic capacitors in parallel so that the load is split over many. Film capacitors cannot be replaced with ceramic or mica capacitors if used for analog signal processing.

However mica capacitors can be replaced with ceramic capacitors in general. Characteristics precision and tolerances. Small value ceramic capacitors are generally used for electrical coupling or decoupling of intermediate circuit stages and plastic or metal film make suitable replacements. The mod i am doing they call it the voodoo chile mod says to substitute the 470pf cap for a 47 uf cap.

I meant 47 uf. I went ahead and ordered the 47 uf stacked metal film caps.
