Ceramic Disk Capacitor Function

Used in power supplies.

Ceramic disk capacitor function.

Small low voltage general purpose capacitor. Ceramic disc capacitor single layer disc resin coated with through hole leads. The plates store the energy until it is needed. Npo click on value to the right to pull up the part.

They are very easy to decode to find the value. The two most common types are multi layer ceramic capacitors and ceramic disc capacitors. Ceramic capacitor definition a ceramic capacitor is a capacitor which uses a ceramic material as the dielectric. Multilayer ceramic chip capacitor mlcc rectangular block for surface mounting.

Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them. The first ceramic capacitor was disc shaped and now it is available in different shapes and sizes. Around 20 ppm c and ceramic with a cte of 10 12 ppm c. When the first two numbers are multiplied with the multiplier the.

Ceramic capacitors come in various shapes and styles. Depending on the shapes and sizes they are used as feed through capacitors electro magnetic interference supressers and even as power capacitors in transmittors. 0 40 as low as. The capacitor contains two metallic plates that are separated by some form of insulation.

The letter j signifies the tolerance of 5. 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. Part number uf v dia. Ceramic disc capacitors are made by coating a ceramic disc with silver contacts on both sides as shown above illustrates.

It has small value capacitance and due to the high dielectric strength of the medium the voltage rating goes up to 1kv. When the ceramic capacitor are layered multiple times it becomes mlcc. This tendency is made worse by ag pd being a much better conductor of heat 400 w m k than ceramic 4 5 w m k so that a thermal gradient will exist across the ceramic layer. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier.

The first two significant digits represent the first two digits of the actual value which is 47. Method of finding the value meaning of codes of capacitor. Small size with high tolerance. Npo 470 1kv disk capacitor 470pf 1kv npo.

High voltage disk ceramic. When this composite structure is heated the electrodes tend to force the capacitor apart. Feedthrough ceramic capacitor used for bypass purposes in high frequency circuits. Ceramic capacitors have a great frequency response due to low parasitic effects such as resistance or inductance.

There are different types of capacitors. Ceramic disc capacitor code label will normally consist of three numbers followed by a letter. Capacitor disk npo 82 pf. The third digit is the multiplier which is 1000.
