Ceramic Disc Capacitor Symbol

It is commonly used in the electronics application of electromagnetic interference.

Ceramic disc capacitor symbol.

On a larger capacitors there is sufficient space to mark the value the tolerance working voltage and often other data such as the ripple voltage. Depending on the shapes and sizes they are used as feed through capacitors electro magnetic interference supressers and even as power capacitors in transmittors. Many larger capacitors like electrolytic capacitors disc ceramics and many film capacitors are large enough to have their markings printed on the case. Method of finding the value meaning of codes of capacitor.

When the first two numbers are multiplied with the multiplier the. Ceramic capacitor polarity and symbol. It has small value capacitance and due to the high dielectric strength of the medium the voltage rating goes up to 1kv. The first two significant digits represent the first two digits of the actual value which is 47.

The first two digits represent the value of the capacitor and the third digit represents the number of zeros to be added. The first ceramic capacitor was disc shaped and now it is available in different shapes and sizes. To gain higher capacitances these devices can be made from multiple layers. I have always been unaware of the markings on a disc ceramic capacitor such as j m and other symbols.

The third digit is the multiplier which is 1000. Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them. An american company in the midst of the apollo program launched in 1961 pioneered the stacking of multiple discs to create a monolithic block. Ceramic capacitors are also called disc capacitors a code of 3 digit is generally printed on the body of this type of capacitors to tell their capacitance in pico farads.

The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. Taking a look at this site today has enlightened me to not only letters on the caps but voltage codes as well. Ceramic disc capacitors have a capacitance value of 10pf to 100μf with a wide variety of voltage ratings between 16 volts to 15 kv and more. The letter j signifies the tolerance of 5.

The early style of the ceramic disc capacitor could be more cheaply produced than the common ceramic tube capacitors in the 1950s and 1970s. Ceramic disc capacitors have a capacitance value of about10pf to 100μf with a wide variety of voltage ratings between 16v to 15 kv and more. When the ceramic capacitor are layered multiple times it becomes mlcc. It is consists of two number disc electrodes and placed in parallel.
