Ceramic disc capacitor code label will normally consist of three numbers followed by a letter.

What is ceramic disc capacitor. Ceramic disc capacitors have a low loss factor a reasonable level of stability and work well with high frequencies. A ceramic disc capacitor is a capacitor constructed with a ceramic disc as the dielectric. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier.

They are very easy to decode to find the value. Youll recall that the basic definition of a capacitor is two conductors separated by an insulator dielectric of some kind. The ceramic disc capacitor is pretty much the standard type used in the tone control circuit.

As a charge is driven onto one plate of a capacitor the extra charge there builds up an electric field. Ceramic disc capacitor values code label. The ceramic disc acts as the dielectric and silver coated on both sides of the disc acts as electrodes.

Ceramic disc capacitors are made by coating a ceramic disc with silver contacts on both sides as shown above illustrates. A ceramic capacitor is a fixed value capacitor where the ceramic material acts as the dielectric. The first two significant digits represent the first two digits of the actual value which is 47.

The ceramic capacitor is made by making a finely grounded powder of a dielectric material which is either paraelectric material like the titanium dioxide or ferroelectic material like the barium titanate. It is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes. Ceramic disc capacitors have two to three digits code printed on them.

Ceramic disc capacitors have a capacitance value about10pf to 100mf with a wide variety of voltage ratings between 16v to 15 kv and more. The third digit is the multiplier which is 1000. The capacitors in which the ceramic material such a paralectric titanium oxide or ferroelectic is used as the insulating material or dielectric is known as the ceramic capacitors.

This type of capacitor is very inexpensive to build and most look very much like figure 1. The composition of the ceramic material defines the electrical behavior and therefore applications. When the first two numbers are multiplied with the multiplier the resulting value is the value of the capacitor in picofarads.
