Substitute For Ceramic Capacitor

Class 1 and class 2.

Substitute for ceramic capacitor.

I meant 47 uf. Yes you are right i made a mistake. 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 capacitor definition a ceramic capacitor is a capacitor which uses a ceramic material as the dielectric. 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 capacitors were first developed in the 1920s in germany as a substitute for mica dielectrics. I went ahead and ordered the 47 uf stacked metal film caps.

The two most common types are multi layer ceramic capacitors and ceramic disc capacitors. Per the iec guidelines. The original part is ceramic non polarized. However mica capacitors can be replaced with ceramic capacitors in general.

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

There are two classes of ceramic capacitors available today. The mod i am doing they call it the voodoo chile mod says to substitute the 470pf cap for a 47 uf cap.
