Ceramic Disk Capacitor Function

Used in power supplies.

Ceramic disk capacitor function.

Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them. Part number uf v dia. The plates store the energy until it is needed. There are different types of capacitors.

Capacitor disk npo 82 pf. Small low voltage general purpose capacitor. Ceramic capacitors have a great frequency response due to low parasitic effects such as resistance or inductance. Some of the most common are.

The third digit is the multiplier which is 1000. When the first two numbers are multiplied with the multiplier the. Around 20 ppm c and ceramic with a cte of 10 12 ppm c. Ceramic capacitor definition a ceramic capacitor is a capacitor which uses a ceramic material as the dielectric.

The first two significant digits represent the first two digits of the actual value which is 47. 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. It is consists of two number disc electrodes and placed in parallel. Ceramic disc capacitor code label will normally consist of three numbers followed by a letter.

Feedthrough ceramic capacitor used for bypass purposes in high frequency circuits. Multilayer ceramic chip capacitor mlcc rectangular block for surface mounting. The letter j signifies the tolerance of 5. Ceramic disc capacitors are made by coating a ceramic disc with silver contacts on both sides as shown above illustrates.

It is commonly used in the electronics application of electromagnetic interference. High voltage disk ceramic. Npo 470 1kv disk capacitor 470pf 1kv npo. The first ceramic capacitor was disc shaped and now it is available in different shapes and sizes.

It has small value capacitance and due to the high dielectric strength of the medium the voltage rating goes up to 1kv. 0 40 as low as. They are very easy to decode to find the value. The capacitor contains two metallic plates that are separated by some form of insulation.

Ceramic disc capacitor single layer disc resin coated with through hole leads. The two most common types are multi layer ceramic capacitors and ceramic disc capacitors. Method of finding the value meaning of codes of capacitor. When this composite structure is heated the electrodes tend to force the capacitor apart.

Depending on the shapes and sizes they are used as feed through capacitors electro magnetic interference supressers and even as power capacitors in transmittors. 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. Npo click on value to the right to pull up the part.

Small size with high tolerance.
