Substitute For Ceramic Capacitor

You are also right the original part is 470 pf.

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. Ideally though again depending on the application use a replacement as a temp. 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 capacitors were first developed in the 1920s in germany as a substitute for mica dielectrics.

However mica capacitors can be replaced with ceramic capacitors in general. 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. I went ahead and ordered the 47 uf stacked metal film caps. Small value ceramic capacitors are generally used for electrical coupling or decoupling of intermediate circuit stages and plastic or metal film make suitable replacements.

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. Film capacitors cannot be replaced with ceramic or mica capacitors if used for analog signal processing. Yes you are right i made a mistake.

The two most common types are multi layer ceramic capacitors and ceramic disc capacitors. Per the iec guidelines. Class 1 and class 2. Characteristics precision and tolerances.

The original part is ceramic non polarized. There are two classes of ceramic capacitors available today.
