Substitute For Ceramic Capacitor

However mica capacitors can be replaced with ceramic capacitors in general.

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. Per the iec guidelines. Ceramic capacitor definition a ceramic capacitor is a capacitor which uses a ceramic material as the dielectric.

Film capacitors cannot be replaced with ceramic or mica capacitors if used for analog signal processing. Class 1 and class 2. 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.

The mod i am doing they call it the voodoo chile mod says to substitute the 470pf cap for a 47 uf cap. Ideally though again depending on the application use a replacement as a temp. The original part is ceramic non polarized. Yes you are right i made a mistake.

Polystyrene capacitors are generally unavailable nowadays. There are two classes of ceramic capacitors available today. I went ahead and ordered the 47 uf stacked metal film caps. In the 21st century the international electrotechnical commission iec currently separates ceramic capacitors into two classes.

Characteristics precision and tolerances. You are also right the original part is 470 pf.
