Ceramic Disc Capacitor

Click here for resistor colour code and smd resistor code ceramic disc capacitors have two to three digits code printed on them.

Ceramic disc capacitor.

The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. When the first two numbers are multiplied with the multiplier the. 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. The early style of the ceramic disc capacitor could be more cheaply produced than the common ceramic tube capacitors in the 1950s and 1970s.

Read the tolerance code on ceramic capacitors. The first ceramic capacitor was disc shaped and now it is available in different shapes and sizes. Method of finding the value meaning of codes of capacitor. Ceramic capacitor definition a ceramic capacitor is a capacitor which uses a ceramic material as the dielectric.

Ceramic disc capacitor code label will normally consist of three numbers followed by a letter. Ceramic capacitors have a great frequency response due to low parasitic effects such as resistance or inductance. An american company in the midst of the apollo program launched in 1961 pioneered the stacking of multiple discs to create a monolithic block. Ac line rated ceramic disc capacitors class x1 400 vac class y4 125 vac.

Please view our large selection of ceramic disc capacitors below. Ceramic disc capacitors are available at mouser electronics from industry leading manufacturers. They are very easy to decode to find the value. When the ceramic capacitor are layered multiple times it becomes mlcc.

The third digit is the multiplier which is 1000. The two most common types are multi layer ceramic capacitors and ceramic disc capacitors. I have always been unaware of the markings on a disc ceramic capacitor such as j m and other symbols. High voltage ceramic dc disc capacitors 10 kvdc and 15 kvdc.

The letter j signifies the tolerance of 5. The first two significant digits represent the first two digits of the actual value which is 47. 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 are made by coating a ceramic disc with silver contacts on both sides as shown above illustrates.
